I hope it wasn't just an "accident" and Google really was working on a way to make it work for both developers and users, and perhaps it was there much like the ART runtime is in there, even though it's not ready for primetime.

I think Google can make it work, but they need to be committed to it. Surely there's a way for the apps to gracefully transition to not needing certain permissions. Google just needs to introduce the proper rules for developers to make this work.
