Budgie, XFCE, Mate, LxQt in the “old but traditional” desktops; all will switch to wayland and no longer really fit
I would also add the category
"I want a stable experience without many changes and accept old bugs that are not fixed for an eternity" (Debian stable, Almalinux, Rockylinux, Opensuse Leap, *Ubuntu LTS & derivatives)
“I want new updates with the latest and greatest but breakages” (Arch, Gentoo, Fedora rawhide, opensuse tumbleweed, Debian testing?)
“I want something in between” (Fedora, Opensuse slowroll, Ubuntu)
