As for the rest, we've all known for decades that Lucas was making up a ton of his story on the fly. There's enough behind-the-scenes documentation to bury an elephant under. But once that trilogy was finished and "in the books," it would've been nice not to keep contradicting it. That goes for Lucas himself, but especially for writers/directors who didn't actually create the IP in the first place.
If it was up to me, and it's not, there would be the Holy Trilogy and nothing else.
On a personal level, I find it bizarre that there are so many Jedi still milling around in the post ROTJ timelines. Lucas sold you out. And all the other fans. If he wanted a pure lockdown on consistent continuity and honoring his original world building, then he shouldn't have sold it to The Big Mouse. But the reality is the longer a "universe" or franchise goes, the more ridiculous it becomes against it's original roots. Basically every "hit" on Showtime is a test case for that (Weeds, Shameless, Homeland, Billions, etc, etc)
For example, I personally end Indiana Jones at IJ-TLC. And everything else is kind of high powered fan fiction. That's kind of how I separate out the things I loved in my childhood to it's current cash grab merchandising pimping bastard self inflicted mess that came a generation later.
But I'll still hold that even the Holy Trilogy had some inconsistencies in it, by the very nature of the organic filmmaking process.
You cannot stretch the world building this far and for this long and not have it all fall apart ( books, video games, new movies, new TV shows, new animation, behind the scenes, interviews, etc, etc, etc) I don't disagree with you in principle, but your expectations are not in lock step with how this all tends to work across the bottom line.
Lucas started out trying to make art. Now it's packaged like it's being churned out by an energy drink company. I'm not dogmatic about his lore because I personally let it all go once he clearly sold out. Sold himself out. Sold you out. Sold me out. Sold out all the fans. This is like U2 secretly donating to the PIRA in the beginning and then evolved into doing movie soundtracks with Bono doing cameos on Entourage.
You want to honor the artform in principle. And I respect that. I truly do. But these are energy drinks. Disney is not a family friendly company, they are basically just pimps that shovel off content instead of two dollar whores at closing time. But the methodology is the same. It's not art anymore, it's glitzed up like an energy drink. But instead of a soul, it's still that same two dollar whore at closing time right down in the gooey center.
It's very likely we actually want the same things, but the difference is probably our expectations on the established process involved.
