Let me describe the philosophy of this project by illustration on a similar point.

The (main version of) this project doesn’t radically alter the plot points, including Rey being a Palpatine, though hopes to make the retconning as congruous as possible with what came before. I appreciate the nuanced improvement we get by replacing Kylo Ren’s line, “I never lied to you” with “You were right.” It has the same retconning effect while demonstrating attention to details that makes it more believable that it was the underlying truth all along.

I’m not sure and will need to think about it (or, more realistically, entertain discussion from you all) to see whether removing that line does something similar. The whole thing is pretty silly, with Palpatine literally doing everything all along and making it so concrete rather than thematic.
