Weren't most of those of in the "there can be only one" vein though? They "killed" Tony & Hulk, depowered Cap completely. Thor stuck around in a different capacity, but lost his Thor role. So those were positioned as taking the place of rather than co-existing with their legacies.
Miles & Peter is unquestionably the most successful one and that is in the vein of Jon & Clark here. They aren't cutting the originals out, they are just shifting the roles or settings slightly.
Movies is a different beast I think. They couldn't recast Iron Man after End Game or Cap and keep the stories going. The expansion of the narratives needed to keep the continuity intact.
