So, according to Jeff (who, again, is as dependable as they come, and I can personally vouch for)...
Damon Lindelof's version of the "New Jedi Order" movie was set 60 YEARS after
The Rise of Skywalker, with a different, older actor playing Rey, the comp for which they were using was Helen Mirren (before having offered her the role) - who, in the face of a new, emerging threat, would have begun training two younger Jedi.
Apparently the script wasn't great, though, and it was at that point that Kennedy decided to switch to actually using Daisy Ridley herself, thus dialing the time period back 50-ish years. Lindelof presumably didn't want to go that route - or wasn't even afforded the opportunity - and so Steven Knight was then hired to execute the new vision.
As much as I love Lindelof... maybe we dodged a bullet? Or does Ridley coming back still feel "too soon"?
