Actually... he did:
Tim Burton did it too, in the scene at the Axis Chemical Plant when Jack Napier first lays eyes on Batman's costume. And later during the parade scene, the Joker quips that Batman was at home (quote): "washing his tights".
There's nothing subtle about this scene, where J. Jonah and his assistant come up with Dr. Octavius' supervillain name, by referencing Dr. Strange. I'd say that's winking at the audience.
That's not the same thing though. In the X-Men scene they're referencing the actual comic, in this they're just making an awkward elevator scene where the suit would obviously be addressed. It's not self referential. That JJJ scene is probably one of the few times the movies actually break the fourth wall, but for the most part the humor isn't referential.
Look, we could be doing this all fucking week just discussing each individual scene in the Trilogy, but that wasn't even the actual point. Raimis has a specific style of absurdity and campiness to pretty much all of his movies, there's really no debating that, he's known for that. All you're doing is trying to claim that some times people have done something similar once or twice, which is just not interesting to me, or practical. Tone is something that should be obvious, it's not something you have to explain, otherwise, it fails. It's like if I was talking about the Shining and you bring up that the paranormal activity movies kinda did something similar that one time. If you don't get the tone of the movie, then there's really nothing that I can say that's gonna help ya. So as to not further waste our time, I'll be going home now.
