Med tanke på hur alla svar på den här frågan säger att det inte finns något sådant som Harry Potter-kanon, men svaren på detta fråga påpeka att Förbannat barn har kallats "canon", skulle jag vilja försöka sätta några sammanhang till Rowlings tweet.
JKR: No, I see that, and yeah, I follow your line there. I can't — I mean, obviously, there are lines of speculation I don't want to shut down. Generally speaking, I shut down those lines of speculation that are plain unprofitable. Even with the shippers. God bless them, but they had a lot of fun with it. It's when people get really off the wall — it's when people devote hours of their time to proving that Snape is a vampire that I feel it's time to step in, because there's really nothing in the canon that supports that.

Canon: brown eyes, frizzy hair and very clever. White skin was never specified. Rowling loves black Hermione

The story of #CursedChild should be considered canon, though. @jackthorne, John Tiffany (the director) and I developed it together.

Q. There were obviously some major changes from the HP books to the films... Are we to take everything in these films as canonical?
JKR: Yes, because I'm writing them!
