Rocky Linux is, I would say, emphatically not a Linux distro for the desktop. This is unrelated to your rhetorical question, but I think your exasperation at "yet another OS" is a bit undeserved here.
This fills a specific need for "enterprise" customers, specifically, being very slow and very stable. It's not supposed to be a consumer OS for doing normal desktop activities on, although there's nothing stopping you from using it as such.
This isn't yet another slightly tweaked fork of Ubuntu or Arch Linux or some such, where maybe that attitude is more deserved.
