I agree with you here, but I have a feeling many Marvel and DC readers wouldn't. While I think it's pretty unreasonable to expect a current story to adhere to another from over 20 years ago, I know there are many that wouldn't.
And that's the thing about comics. When they were first conceived, readers were supposed to move on at some point, replaced by a new set of readers. Instead, very few new readers are coming in because superhero comics have become increasingly insular and gatekeep-y, which is certainly not a good thing for the genre.
