Google is the primary champion of PWAs, they have a vested interest in its success. The reason I focused on Apple is because its actions are one of a profit-maximizing gatekeeper actively defending its most lucrative business against an existential threat that is PWA. Every bug, every delayed feature, and every artificial limitation imposed on PWAs on iOS is a calculated strategic move in this defense of its walled garden that makes maximum taxation possible.
>PWA's just never took off.
That's just the lazy manufactured and false narrative that I've already thoroughly debunked. I'm not going to repeat it, since you would just ignore it again.
-But it's less pain than trying to turn a generic Android tablet into something more like a kiosk, best I can tell (there are third-party apps that do this, which survives reboots, I'm led to believe, but I'd rather not mess with third-party stuff). I previously made Android apps in Java for the tablets, and while I enjoyed the fragment system it uses, the permissions handling was always a nightmare whenever I wanted to do something neat or experimental -- TTS and mic listening in a PWA makes me much less frustrated than trying to do it via native app (which seems backwards to me), and I can still use the website on any non-Android device.
