@Jonathanglick @jonah In my opinion, the problem is less technical & more administrative. Off the cuff, permalink is artificial - we could have made it relative w anchor determined by user address. The bigger problem is from the new host. The admin has to moderate the old content in bulk for they can not depend on the old admin.
@aswath I was thinking of permalinks posted on sites outside of the fediverse where they wouldn't be dynamically updated, but that certainly could be solved with redirects or something too. That's an interesting viewpoint though, that makes a lot of sense. Sounds like a moderation nightmare!
