I'm not sure I buy that; the Drastic UI is a bit odd on Android as it uses its own game-style renderer for UI rather than Android UI. But I frequently find apps that give you an actual warning when launching that the app is out of date (in terms of target platform and API level) and you should contact the developer to see if there's an update; and often the permissions API used pops up the "old style" permissions UI where you have to accept all, rather than granular permissions. Those apps haven't been taken down, to my knowledge, and I still come across apps that do this as recently as last week. Drastic doesn't have such a warning, and it uses the modern granular permissions API.
