I don't really think this is Marvel's desire to stick to a particular status quo. They were perfectly happy with Felicia being a Femme Fatale thief for quite a while.
If I had to guess- which probably isn't accurate- I'd say it might be a mix of "Let's piss people off to get their attention" and the particular creative parties on the book believing that certain characters have to exist in a particular box, or preferring them a certain way.
