I think it’s a difference between having an apprentice (which makes you their master whatever your rank) and being a Master of the Jedi Order, or a Council-level Master, which is a whole other formal thing.

Either way, definitely each to his own, but when canon bends to create new content, the user has a choice of whether to accept the bend in order to enjoy the new content or not.

I’m happy that Vader’s Luke’s father, because that gives me good stories, even though that was a bend of canon not intended during ANH. I’m happy Leia is Luke’s sister, because that gives me good stories, even though that was a bend of canon not conceived until ROTJ. I’m happy that Ahsoka is Anakin’s Padawan, because she’s become one of my favourite characters, even though that was a bend of canon when it was created.

It’s a negotiation between you and the writers: We’ve got a good idea, but you’re going to have to accept this new interpretation of what you may have understood before. And sometimes that means that earlier content loses some value (the Vader suprise, the Yoda reveal), but you have to decide for yourself if the new stuff is worth the bend. For me, new stuff adds way more than it removes, so I’ll take that deal almost every time.

But adding new stuff by bending the rules has been part of Star Wars since the very first movie after the original.
