Or maybe we should all really have a master or delegation key with with we can co-sign a lower key, like someone was saying in the other thread. Then we could use that to sign the burn. Makes key management complicated, tho.

It's a hard problem. The only simple thing I can think of is leveraging nip05, assuming you still have control over your nip05 you can use that to point to the new official npub. That wouldn't mean wot should pay close attention to nip05, ie, if/when it changes domains or etc. you would want to keep nip05 steady and grow trust with that.

Oh, that's clever. That is really clever.
