Curious way of seeing it. I’ve never considered a new major version as being an entirely new OS… Do normal users even consider new Windows versions as anything but a UI “upgrade”?
If you don’t want version numbers maybe you should run a rolling release distro? I don’t think you’ll be able to convince everyone to stop using them. They’re quite instrumental when dealing with old systems on LTS versions when having to deal with EOL.
Or maybe this post is more of a “I just realized”-post?
