Most Linux distros are not Arch either. It would be nice to have more support for this use case in general - like something one can configure easily during the initial OS setup.
I use OpenSuse so I had to use the guide for Fedora, but there were some differences as far as I remember.
”Fedora, RHEL, CentOS, Rocky, Alma” are all the same distro group: Enterprise Linux (EL). That it's ”available” on other distros is irrelevant, almost anything is ”available” as a non standard choice for any distro.
