F-Droid has spent many years trying to step out of the "only for technical/power users" into the "This is a tool that normal phone users should have and use". A one time 24hr wait moves back to the "F-Droid is only for technical users" big time.
Bought a new phone? Moved from iPhone to Android? Want help from your friend/family member/librarian/other to setup your new phone for getting apps? Sorry, you need to come back a day later before you can actually use it.
Guess what the normal/non-tech user does in this 24hr period? Go to Play Store, install a bunch of apps, forget that you had the desire to use an alternative.
This indeed does make F-Droid no longer a tool for normal people, but only a tool for those willing to do a bunch of "Advanced" things on their phone. By definition, not regular users.
