Well Obtainium already can access ADB from on device through the Shizuku framework. I use that to update APKs in the background for example. But it's a super hacky solution and not going to be used by most people.

There is an ADB app that I use very often on Android TV and Google TV to uninstall bloatware (can't remember the name)... So, it's possible. You'd have to enable the developer options first and all that... But that's always the first step of buying an Android phone 😅, at least for me.

I just run a system without Google Play Services or any other Google Apps at all. No more problem.
