Recover means changing npub and hinting in an unforgeable way that your followers should follow you in a new npub and complaint clients auto following the new npub after a period of time

Would you need your old nsec to do this? i.e. would this work if your nsec was lost?
Cool. Yes I like that idea. Losing your social graph is probably the most devastating part I can imagine of your key becoming compromised. Could it potentially be coupled with a way to migrate certain content to your new key pair, like if you had a backup of old notes that you trusted? It wouldn’t matter so much for many short notes and replies, but for others such as articles or something you want to maintain for historical reference, it would be good to have a way to migrate them to a new account.
