It has been said that "the novelizations are canon until they contradict with the movies". From that you can argue they are or they aren't canon. The point is, as it has always been, that the film makers don't care of the books, novels,... when they made their movies (hence the old canon rankings which still exist if not by name).
But is that worst than the new policy to retale a story in a story so the first story is half canon ? You know what I mean if you know Star Wars Adventures, some of the Junior Novelizations, All Creatures Great and Small, Phasma novel, The Legends of Luke Skywalker and last but not least, From A Certain Point Of View with no less that 40 stories that contradict between them and can hardly considered canon. So nothing is sure in these stories, if a future inconsistency appears they will be like "hey, you know the story of this book never happened, it's just a in-universe fairy tale". And there's more and more of this half-canon stuff.
