All these debates about consistency within character and lore really shows how empty the discussion is when it comes to the current story going on. Any mysteries are too mysterious they’re virtually absent until we get to hear about them.
If these were adaptations of books I think the sequels would be comparable to The Hobbit movies, rushed and padded, a trilogy for the sake of it. There was no question the new movies would be a trilogy before it even started but so far there just isn’t much information to grab a hold of, lot of meandering more in line with a 10 year build up similar to the Marvel formula. Now IX feels like it will itself be a soft reboot of this new trilogy, this time packed with all the story we were supposed to be following on top of its own developments, all while trying to send up the whole and conclude the entire Skywalker saga. My prediction of how the audience might view this in hindsight is that TFA and TLJ will feel like an overextended prologue while TROS will be this mega movie, the one you skip to (RotS anyone?), backed into a corner and ultimately too bloated to gracefully end the ride smoothly, if even intact.
