Well, yeah, the more you think about the whole erase the ship and crew from history and swear everyone who knew about them to secrecy the more it falls apart. But, Kurtzman's interviews do seem to indicated that is indeed what is happening, Because Canon. It's silly, because of everything snowballs, eg, erase Michael's mutiny and the Battle of the Binary Stars is erased, as is the Klingon War. So, there was just a day when a bunch of Starships ended up in the same binary star system and got destroyed because reasons. And yet, I know that when Disco arrives in the future and try Googling themselves, they'll discover they never officially existed. Indeed, I have a suspicion this whole don't officially exist thing is going to eventually become a plot point in the Section 31 series explaining how they become the ultra secret hidden in the shadows organization we saw in DS9.
