The "development interest" in Wayland is still mostly carried by corporate full time paid developers. Wayland as such has had zero community mindshare in the FOSS ecosystem (until Hyprland came along but that is literally just one guy). And for a reason: The protocol is not suited for Desktops at all. It was developed for car entertainment systems and mobile phones. As a result it makes things that should be simple (like creating a window, printing a string, taking a screenshot) incredible hard for developers.
