Whether or not HAL, pappasketti, and others decide to go the Rey Nobody or Rey Palpatine route, it would be such a mistake and waste of time to retcon their excellent and really PERFECT edits of TFA (HAL9000) and TLJ (poppasketti) to try and fit into the new, mediocre TROS story. Rather, the focus should be on making TROS itself more streamlined and coherent. The discovery of Palpatine should have been a real surprise, and now that that surprise is ruined it doesn’t help to make Palp cackle somewhere in TLJ. Just remove his mention from the awful opening crawl from TROS. Perhaps if the whole Rey Palpatine storyline was something JJ/disney added in at the last moment, it is better to just reverse that arguably silly and unimaginative decision in the edit.
