https://minds.com/ proposed NIP-26 because they didn't want to have full control over users' keys, but I am still confused about what exactly they wanted to do with that. I was thinking about a process through which a hosted key slowly signals that it is in fact an "adopted child" of some parent key created elsewhere, then readers can slowly migrate to following that other key. This could be done with NIP-26 but that is not necessary even, there could be just a pointer and a hint. Is there a problem with this?
