And by what mechanism can you prevent google from disabling adb? Or implementing a situation like iOS where sideloaded dev apps only last for a week and are signed with your personal developer key tied to your credit card?
There's nothing to stop them, and absolutely no reason to think they won't take away adb sideloading in the near future.
