Well that is kind of what we have. Writers can indeed write what they want within a quite broad latitude, and in general the very next writer will tend to do their own thing with variable and often cursory nods to previous continuity. I don’t see why that’s a problem. It has been the same for decades.
It is notable however how few examples the OP uses before reaching for the Spider-Man marriage. The last thing we need is another thread about that.
