Since it’s very unlikely that we’ll hear more about this officially from Disney, and people have already inferred the various possible reasons why this happened (and no one can really prove one over the others, if that even matters), that part of the conversation is essentially a dead end, particularly because dancing around political or quasi-political things seems like where things go next. No interest in that.
Instead, we can discuss what happens from here. My guess is that Slave-I isn’t gonna get renamed, as even Disney is smart enough to know that that would cause even more consternation among fans. It would be pretty easy to keep having the ship appear, and never have anyone refer to it by name, as happened in the OT.
Now that they’ve kinda made a mess of things by upsetting the status quo, though, perhaps the easiest way for Disney to deal with this is to just have Slave-I get destroyed early on in the new series. Then Boba gets a new ship, with a new name. Problem solved, as far as they’re concerned.
