Kylo was already lying about Palpatine wanting her dead as a child in the theatrical cut, right? Doesn’t Finn learn from D-O that Ochi’s job was always to take Rey to Exegol? At least I think that happened, and I think it was supposed to be a twist. That ‘reveal’ also makes more sense if the audience doesn’t already know Palpatine has actually been trying to kill her.

My only concern is the effect this change has on Kylo. It’s not a big thing, but the only reason I’ve been able to guess for why it is the way it is in the theatrical is because JJ/Terrio wanted it to be very obvious that Kylo is disobeying Palaptine, because he needs to be ripe in the audience’s eyes for his second act redemption, and I wouldn’t want to do any significant damage to that. We only explicitly learn in the hangar scene that his actual plan is to have Rey join him so they can use the power of the dyad to usurp Palaptine, so with this change it’s more of a mystery before that whether Kylo is or isn’t actually going along with Palpatine’s orders. Maybe that’s a positive though - it helps prevent the audience asking questions like “if Kylo wasn’t really going to kill Rey, and instead wanted her to help him kill Palpatine and take the throne, why didn’t he just go through with stabbing Palpatine in the face at the start of the movie when he had the chance?” or whatever.
