A compatibility layer for Android apps would really make it viable. I just don't want to fight my OS to be recognized and treated as its owner.
In that respect I really like how I can run Windows games on Linux via Proton and Steam; an otherwise good game can ship with all kinds of crap (like having their own launchers stuck in the system tray), but when I'm done the whole Wine-sandbox collapses and I'm back in a Linux desktop that does what I want. Something like that for the host of proprietary apps you are nowadays hard-pressed to avoid (I manage now, but it is not a tenable position) would be welcome. Ideally you could do all sorts of privacy preserving stuff at the sandbox layer.
