Here is something that people need to understand: If something is a point of contention narratively and/or has not been internally agreed upon and established, it will not be commented upon by Lucasfilm or associated/affiliated individuals. It does not matter if the thing in question has been previously established onscreen or in a supporting Canonical source.
I know this because I have personally witnessed members of the Lucasfilm Story Group either directly shut down a particular idea that has been ruled out of being part of the official Canon or deflect a question because they were not at liberty to talk about the subject of said question.
The very fact that Rian, Daisy, and others have stated that Rey knows who her parents are is as loud and definitive a Canonical declaration as if that fact had been explicitly stated onscreen.
And yet here we are with IX coming, and apparently it’s going to put it to bed in some way.
So all of those people might well know this.
But we still don’t.
Because the film the finally finishes the new trilogy (which so far seems to have taken a few days, maybe a fortnight, of the characters lives...) isn’t out yet.
If it wasn’t an open question in some manner, if TLJ had put it to bed, would Daisy have recently said that IX will answer that?
I mean you are basically saying they will no comment stuff or not answer. That’s...not quite the same thing as confirming anything is it?
We will wait and see I guess, but SW works traditionally on fairy tale logic.
Princess Leia can probably pee through twelve mattresses or something....
