How is it irrelevant if I can only use my recovery authenticator for the services I’ve enrolled it in, yet enrolling multiple physically separated authenticators is a huge pain practically?

It’s like changing the locks on various doors in my house every other week and trying to have a copy of all keys with friends or relatives living out of town.
