I don't think this is controversial at all. Shiki is canon, but majority of the One Piece community knows it doesn't really mean Strong World's events are.
The same goes for Film:Red. Uta is canon, the events of the Film aren't. The only "controversial" thing I can see coming out of this is Uta potentially making an appearance in the manga, but I'm gone assume she won't, just like Shiki.
