I think making it her de-facto name in the movies makes it more then an Easter Egg.
It's more of an update on the entire Spider-Man mythos. I mean, they even use elements from Ultimate (although I don't think we needed mutant lion man Kraven).The cartoon? I think that's kind of a updated, improved version of the early 616 ASM comics, at least how I see it. Since I preferred the Ultimate iteration to 616, that's why I was hoping that they'd skewer more to that then not.
The real shame is that they needed to give her powers to actually make her relevant on that show. And she still barely got to do anything since the show was practically over by then.
