This is the important bit of Schrödinger's Canon
"But the primary creator is still working on the work in its primary medium, and is under no obligation whatsoever to include these extra bits in the next main installment. They may not even be aware they all exist. In really large and ill-overseen Expanded Universes, even bits of the expanded material may be self-contradictory. Two characters who got on great in the main story may become romantically involved in a comic, while in a novel they grow distant, while in a video game they just remain friends. Which, if any, "actually" happened? We'll have to wait until the next primary installment to see."
In other words, this requires the existence of installments after this Schrodinger's Canon work to judge whether it's truly canonical or not. It requires hindsight.

Having looked at the two tropes, I'm trying to see if there are examples as such, but from what I understand:
Despite having some conflicts with the anime, I noticed one of the One Piece movies was listed as Schrödinger's Canon (I saw on the Non-Serial Movie page there's a fair few of them) even though some of it conflicted with canon.
My basic question is, are the two tropes mutually exclusive or not, before updating the trope pages or work pages - I'm slowly wick-checking both tropes.
