Although I use sway, I used KDE for a long time and XFCE prior. They’re both phenomenal. I’d love to see XFCE make its way to wayland in the future.

As an aside, I feel like Wayland has a market ripe for the introduction of lightweight DEs. Sure, it has the very lightweight (hyprland, sway, river, dwl) and heavyweight (KDE, Gnome) but nothing between like XFCE, LXDE or MATE
