If I understand correctly, the F-Droid store itself would be possible to install without waiting period, as it's an app from a verified developer.

Would apps installed from F-Droid be subject to this process, or would they also be exempt? Could that be a solution that makes everyone happy? Android already tracks which app store an app originates from re: autoupdating.
