Yes it does. Your whole display server is your desktop/WM when using Wayland. Using the newer versions you get things like VRR, HDR, fractional display scaling and so on.
In the last year I was intentionally using beta packages of KDE Plasma to get stuff like touchpad gestures early. Even now, Plasma makes important developments like HDR and explicit sync so yes, it still matters.
