I actually do just that: https://twitter.com/phhusson/status/1447824974396497924 https://twitter.com/phhusson/status/1447824974396497924 My oldest supported device is Pixel 1 (released in 2016): https://twitter.com/phhusson/status/1454155975515152387 https://twitter.com/phhusson/status/1454155975515152387 I'm pretty much alone, and do it in my spare time. So, it's fairly easy to do. Actually, Google do provide some GSIs: https://developer.android.com/topic/generic-system-image/releases https://developer.android.com/topic/generic-system-image/rel... But they are unusable as daily driver on the majority of devices. Many (I'd say most) devices simply won't boot, most devices would have no in-call audio, there wouldn't be VoLTE on any device, backlight control would be broken on many devices, etc. etc. Google doesn't do it because they have no incentive in doing that.
