I still remember the windows Xp compatibility problems with old software and games. And windows 10/11 didn’t make those problems go away, instead it got worse. Old software is not a priority, understandably.
For example have you tried to play Dungeon Keeper 2 on a modern pc? I have, and it crashes constantly. Other software won’t even run a lot of the times, even with tinkering.
DOSBox made using DOS software accessible. There is not a catch-all like that for pre XP windows software yet.
Also this community is mostly for/about nostalgia.
