I would personally leave Rey’s admission about her parents as-is in TLJ, but that’s mainly because in my mind, Rey Nobody will be the true “definitive” version of TROS, and it will be important with that version that Rey accepts, for herself, that her parents don’t matter. If it’s just Kylo doing all of the talking, it deflates any sort of internal character struggle.

Also Hal, if Snoke has been recontextualized as “henchman” rather than “clone,” will you want to go back and remove that blue smoke that was added in TLJ:L V4 when he dies? (We could always chalk this up to, “Wow, he’s such a weird alien species! Look at that face! And his body is filled with blue smoke!” if you don’t want to go back to that one.)
