I mean, I just don't like retconning in general. It's something that makes me nauseated and I try to avoid it when I can. It's one thing to fill in blanks, it's another thing to revise a known history.
It's a given that our cultural norms and standards are different now than when they were 25+ years ago. But there's a better way to deal with that than Aaron saying, "hey, you know all those issues Byrne wrote on She-Hulk? Well, Jen was secretly harboring pain and frustration over her sexual identity and gender role." Because she was very vocal about her comfort level with her identity at that point.
