Neither does BlueSky… or if they do “have” it, it’s never been used because there is still only one server.

You're not wrong but you're also not fully right: there has been a second instance that the devs have been using to test out the federation code. It's not yet open to the public because they are still working on the implementation. At the protocol level, it is very much there, but you are right to point out that the advantages haven't been fully realized just yet.

That makes sense. I guess I would just add that the users don’t know if it’s a good experience yet.

Maybe it sounds good on paper but in practice it amounts to a nothingburger and is essentially the same as manually moving instances in the fediverse.
