Imo not really. I mean, sure comics themselves have a certain status quo that supposedly needs to stay in tact, but there are plenty of very popular stories from even DC and Marvel about their most famous heroes retiring or actually aging along with the comic run.

You just apply that same logic to the movie universe and boom, done. You don’t need to treat the movies the same as the “mainline comic continuity” where there “needs” to be that status quo, you should be treating the movies as those one-off stories where the heroes grow and evolve and eventually retire.
