Something that doesn't support it is realy old hardware already and in 2017 not many gamers will have such and even OSS drivers will have support of it. So if someone would like to create modern and powerful engine that it should be ok. Ofcourse "powerful" engine doesn't sound nice when you have 1 developer but its his choice anyway.
The debate is a little silly, though. If you spend $8M dollars developing a game, most of that will be graphics artists. You can afford to pay a dev for 6 months to produce "a lower quality graphics engine" that will work on Windows Vista era graphics cards (== OpenGL 3.3). If that is pushing your budget, realistically you'll not support Linux long before you don't support people on Windows XP...

Reason for wanting OpenGL 4.4 is AZDO.
But here is the catch... If You do not need tesselation? Mesa will have AZDO faster then OpenGL 4.4
After all AZDO is "just" a bunch of extensions, and Mesa is famous for cherry picking which ext. gets support next
So OpenGL 3.3 + few extra extensions should do the trick (Or 4.0 + few extensions if tessel is necessary!)
"I MUSTA HAVEA 4.4" is relict of monolithic proprietary drivers, where company politics dictate gradual development (no 4.4 before 4.3 is finished, no 4.3 before 4.2 is finished, and oh that hw wont get 3.2 .. because!)
And "I MUST HAVEA Compatibility Profile" is another sad example.
(Thankfully, Mesa allow for overriding both supported version and supported profile... And then some software just magically start to work :P )

Nice idea, but...
Nice idea, but ideally I can wish them not to stop half way and consider opensource driver as primary target at Linux, just as Intel did. But still, nice idea since it is kernel module what is attrubuted to most Linux troubles.
