The other problem with this is that this is all controlled through the Play store API, not your device, so they can yank your access to all of those unverified apps any time they want and say "actually, no verification = no run, fuck you, pay me"

If you don't think they will, that they're not just dying to do exactly that and squeeze people just that little extra bit more for YT Premium subscriptions or whathaveyou, ask the people who had their movies yoinked from their library with no warning by Sony (over fucking licensing costs, at that, not even hurting their profits directly) if they thought that would ever happen and how it worked out for them.
