It sounds like #Bluesky made core engineering and design decisions different from those made for #ActivityPub, and so it's not trivial to make the two systems play together nicely.
In particular, Bluesky puts more emphasis on user accounts over instances with solid account portability. It's not clear how Fediverse would/should react when seeing that an account has moved its hosting to a different repository, just for example.
