Whether or not it's canon is yet to be seen.

It's a crossover with another franchise, which so far have not been canon outside of their isolated, usually-temporary quests.

But it's also an alliance raid, which so far have been canon to and provided additional information about the wider FFXIV setting (Allag, the Crystal Tower, Mhach, Goug as the predecessors of the Garlean race, more details about how auracite works) as a permanent and integrated part of the wider story. They are part of "the canon version" of what our character has achieved, when referenced by static sources outside of the game such as the lorebook and side stories.

So, is NieR automatically "not canon" because it's a crossover, or is it canon because it's an alliance raid? We don't know yet... and some of us are wary of that.
