What I miss a lot is to be able to have a kind of "virtual" android running in a cloud instance. That could look legit to Google to not be restricted by integrity check and all. But there I could share access to my single instance to my multiple non Google non play store devices, eventually sharing access between multiple persons...

Like for example, every crappy things like banks nowadays requires their own shitty app. It might be a pain in the ass to share between phones or to reinstall if you lose or change your phone. And all these useless app consume really a lot of storage resulting in my phone's being always full.

That would be perfect to access it in a kind of remote access for use once in a while.
