Who wants it? I do. Customable of course. 
On the Hapax itself 
Personally I would rather the squarp guys focus on functional features and bugs than fluff.

Main reason would ofc to save the screens which is important, but would be nice if you in the future could customize it like SP-404 mk2. Make Hapax more personal. 
Flying Toasters, please!
In all seriousness, everything Iâve read about monocrome OLED burnout/burnin/pixel dimming is all over the place. Some say it can happen in a month, some say itâs fine for a year, some say it depends manufacturer to manufacturer or even panel to panel.
But the most quoted figure seems to be â50% brightness after 10,000 hoursâ. That is, if a pixel has been on, full power, for a total of 10,000 hours, it will illuminate to only 50% of its original brightness.
Now, I donât think the HAPAX displays pixels at full power. And I, at least, donât leave it on for hours on end. But pixels wouldnât have to degrade a full 50% in brightness for âghostingâ to be noticeable. And seems reasonable enough to just switch off the displays after X minutes of inactivity â even from just an environmental standpoint. So why not? Better (screen) safe than sorry.

have you seen what happened to Electron octatrack screens before they added screen savers?.
display units at music shops were unreadable⌠people wanting replacement screensâŚ
i think its probably a good idea before these issues start to at some type of screen saver

It doesnât need to be an advanced screensaver/power off function. Newer machines like Oxi One, SP-404 mk2 etc. has this. Must be a reason why they have implemented it. But I agree that this function can wait. First bugfixing/UX improvements.
Was going to reply last night, too tired.
I completely understand the issue. Just donât think itâs an immediate priority, specially not customisable.
Iâm sure squarp have limited resources. Something that could be solved as simple as switching the screens off after a configurable period of time, with an option in the settings, could be done.
Note if your worried atm there is a contrast setting for the screen so you can turn that down which will dim the screens.
As for shops, not sure this is a issue since there are plenty of back orders to fulfil.
EDIT:
Also I would assume that they will be covered by the squarp 2yr warranty.

Only problem is if you forget or have one too many beers one night and leave your gear on the screen can burn in⌠these screens seem to have a lower brightness and less of an issue but still⌠guy was trying to sell me an Octatrack at the shop and I was like is this is a defect unit? Didnât buy it and was hundreds of dollars cheaper because of the screen
Well that will be an expensive drinking hobby 
They are extreme situations though and given how quickly Hapax loads, saving and switching it off if you go away for a length of time and booting and loading is like seconds.
If the octatrack was significantly cheaper it was because it was a demo model with screen burn. Doubt it would be that amount off without screen issues. Not sure how shop display models are relevant though, there are always going to be some risk/issues with purchasing.
as above, I doubt leaving it on for one or two nights is going to cause burn-in 
as @ChilledPanda pointed out, a demo unit has probably been left on for weeks on end⌠so not the ânormal caseâ ⌠I donât have any issue with my OT, which has been left on for a while (even pre screen blanking)
all that said, probably just a screen blanking after N minutes of no-use would be best option.
would likely need to be config option, since who is to say what N is⌠for some 15 mins might be enough, but others might want 30 , or 60.
donât know what the hardware (display) supports⌠but given we already have a contrast display,
then presumably the unit could blank the display, and then turn down contrast/brightness.
might save a tiny bit of power/wear.
( I tend to have the contrast down on mine anyway⌠just out of personal taste)
anyway, raise with Squarp via their website - as per normal for requests.

Yeah think is different brightness and screens used compared to the Elektron gear, definitely something to consider though⌠but may have all ready been tested
I would still love a screensaver. Mine is on a lot of the time and it does start to worry me.

I constantly âswitchâ pages to eliminate the risk of burn in. 
i would be down with a saver that turns screens off

This is something REALLY useful, I had the same discussion at Polyend for the Play and Tracker (specially the Play as it screen and UI can create ghosting in pixels quite easily.
If you see Elektron products from MK1 (which screens doesnât dim or turn off) pixels tend to die/ghost A LOT. Digitaks and Digitones screens (or Octatrack MK2) age much better.
HAPAX screens seem âdimmedâ compared to Play or Elektron devices, but I think this is an easy and convenient development for all machines with OLED screens.
I honestly havenât noticed any burn-in or dimming on any OLED devices I have owned. And I have certainly been lazy about leaving devices turned on.
I turn off my Hapax when Iâm done using it, but otherwise the screen is on all the time. 10,000 hours is⌠a loooong time for sequencing. A display unit in a store is going to be on pretty much the entire time the store is open. So any screen dimming is going to happen way sooner than someone would see when using a device at home normally, especially if theyâre only using it maybe 10 hours a week. Some of the examples here are under quite extreme circumstances that donât reflect normal use (like store display units).
I think the screen timer is probably the best option. A visual screensaver/âvegas modeâ just is asking for trouble with bugs imo . And the device really doesnât need more bugs.
Also, itâs much more likely that the potentiometers will fail long before the screen does, if anything. But thatâs more of an issue for the Pyramid, since you rely so heavily on just one encoder with less buttons for functions.
This for sure.
In terms of saving the screen, how about just a timer that puts it to sleep
