Wayland multi-seat + idle-inhibition HDR + variable refresh Fractional scaling (I think XFCE has some/all of this?)
We're just playing catchup to MacOS for over a decade, and soon enough Linux will have to compete with 3d desktop environments (Apple Vision Pro interface). I think we're almost to the point where the DE will be just a physics simulator (game engine) to help augment your reality.
Anyway, I still use XFCE on resource-limited hardware but Gnome has been the only option for a while because progress isn't being made by other DEs on these critical things (color, refresh, alpha-composition, and some wayland protocols missing in wlroots).
I'm just glad Gnome isn't the dependency hell it used to be, and has slimmed down. I really love what they've done with GJS but I believe there's a competing KDE bindings project.
