I don't agree that this is something that should be restricted to "advanced" users, even. One of the basic freedoms that protects users from the unilateral control of the developers, is other developers (like me) being able to patch apps and distribute them to friends and family, without making a public fork or meeting play store requirements. Take for example, youtube revanced. If I want to help my friends by making a private f-droid or obtainium repository, to save them the trouble of going through the (legal!) process of patching and updating the app themselves, right now I can do this. If this requires going through a lengthy process instead, that may or may not be detectable by apps that will then choose to cease to function (this has happened with rooting), my ability to help friends and family as someone with the know-how and experience gets reduced significantly. There's many things that don't fly on the play store, such as the completely legal NewPipe, AdAway, and Termux applications, and while I can sign up for the developer verification, it's not clear to me under what circumstances the verification can be terminated.
