That’s just (big 2) comics in general unfortunately
Sliding scale ‘continuity’ is a flawed concept that’s plagued Marvel for the past couple decades. It was the late 90s/early 2000s when they decided definitively that yea we’re not gonna slow age the golden goose (Spidey) anymore; no kids, no family, and later no marriage. We saw the trickle down effect where a buncha shyt happens/has happened to the Avengers, X-Men and F4 that should lead to certain characters being aged out, retired, or dead for good (see: Wanda/House of M; or Hulk/WWH) but that’s just not the business model like it is for manga. Instead everyone is brought back and all cataclysmic events are swept under the rug with vague references at best.. bc Peter still needs to be 25 years old 30 years from now doing the same shyt when we’re all geriatric.
It’s why the 08-19 MCU despite its flaws and source material inaccuracies was the best storytelling, it had a definite beginning middle and end.
The sliding timescale that Marvel uses is the best compromise. It's around 4-5 years to 1 real year, so Peter is about 30-ish now...but he's also a modern 30, rather than a 30 year old of 20 years ago. Plus, he was married for decades, even though he never had a kid. But they're all aging, and most characters are natural progression. Hell, he was only in HS for like 3 years real time, but for some reason, everyone seems to envision him as a teen. They're never gonna kill off most characters permanently, not their cashcows. That's not the American model, nor would they want to completely age out their target demo. Plus, most of their younger newer characters do not take off, so who's left?
The MCU has it's own problem in that their main/original cast are pushing 50, yet they still want to make movies. They haven't been successful with their younger counterparts either, and Tom Holland pushing 30. All roads lead to the same place in resetting or recasting, hoping the new actors take off. Which for one generation, they would but for the older prior (louder) fans, they more than likely won't.
