Most crossovers I've seen are treated as canon, even if they're rarely mentioned.
It's just a case-by-case thing.
I hope we have the same understanding as to what "canon" is, though. Perhaps I shouldn't use that word in the first place...
What I meant is that usually, stories (especially ones released after the crossover) wouldn't acknowledge the crossover in the past. What I'm more interested in, is for works that do acknowledge their crossover.

I mean, unless they suffer from Continuity Lockout, most works don't constantly mention past events.

I wouldn't ask for "constantly". Just some Continuity Nod would be nice, you know?
I mean, yeah, I guess? But again, this does happen in crossovers I've seen.
I'm not really seeing what the issue is here...
I'm helping!
I was introduced to the concept of crossovers through fanfiction, so the idea that "crossovers remain canon in source works" is the default kinda baffles me.
Trouble Cube continues to be a general-purpose forum for those who desire such a thing.
I don't get the thing behind Fake Crossover.
Isn't it the norm that crossovers aren't "canon" to the works' timeline? And thus it's more notable when the crossover is in fact acknowledged as canon?
