Disney wanted all one canon. Just so you had to buy every comic, book, video game and watch every show. Its cross merchandising. Its like when Lucas didn’t show the clone wars on the movies and expected you to buy into all the other ancillary material to know about them. Its cynical and driven by profit. Not so good for story, but great for corporate driven interests.

A consistent canon is only possible through editing and retcons. Like in Tolkien for instance.

There is another kind of internal consistency though like the rules of the universe can’t be broken like you can’t Hyperspace skip, can’t lightpeed a ship into another, and can’t lightspeed through shields or go to lightspeed in a planets gravity well. You can’t teleport objects, force heal like a videogame. You can be a Jedi if you have the aptitude and apply yourself and you don’t need midichlorians.
