> No one would argue that Luke isn’t a Jedi Master
Luke himself would probably argue that he wasn't worthy of the title. He just took the title because he was the only one around who was in the position to start and lead a new Jedi Order. Secrets of the Jedi is a reference book written from his POV and it reveals that he always felt insecure about that title given that he didn't have all the knowledge/training opportunities previous Jedi had.
> By the old standards I don’t think they’d even let him train at the Temple.
The old standards, and everyone that upheld them, are dead. There are new standards set forth for what it meant to be a Jedi. Yoda "knighted" Luke so Luke was free to rewrite things how he saw fit.
I also like the change to young Anakin as well.
The Secrets of the Jedi book has something where Luke mentions having talked to Anakin. I don’t really recall what it says. That is the only example of Luke talking to ghosts in the new canon that I know of. I’m not sure if any ghosts spoke to Leia.
