idk how controversial it would be but i have been thinking about nip05 follows recently. like you can change npub, but your followers stay the same. good for account recovery, and post quantum stuff.

but i think instead we can just like uhh, do it client side kinda? detect current or previous nip05s of an npub we have been following changing npub, might give you some sort of notification? so you can look into what happened? but thats kind of manual. yeah idk. fuck it.
