Please, build XFCE4 for EPEL10.
This is likely to be impossible currently. We need: an xorg stack/server (which rhel10 doesn't ship, but could be shipped in epel I suppose if anyone was crazy enough) or wayland support in Xfce (hopefully coming more in 4.22).
It's wanted even without Xorg as you can use it with remote systems, like TigerVNC or ThinLinc.
+1, we use it for remote systems via VNC-based software.
+1 from here, we use it for VNC sessions which have to be lightweight
