Not to mention all the taglines like "the story beyond the original!", "the last episode!", "the Naruto that only Kishimoto has envisioned until now!", etc. Adamantly classifying it as non-canon at this point frankly strikes me as being intentionally obtuse. In this specific situation, I think it would be more prudent to assume it's canon unless stated otherwise.

Kishimoto had this level of involvement in Road to Ninja as well. You're overhyping a situation that doesn't need it. When and if Kishimoto says the movie is canon, it is. Until then, it isn't. That's all there is to it.
