The only thing that Wayland standardizes is multi process GPU memory access. Neither GNOME nor KDE (which are far more popular Wayland implementations) use any of the wlroots "standards" and thus they can not really be called as such. Also wlroots does not define one bit about toolkits and widgets. > Anyone is free to extend the protocol with whatever they want The protocol itself is very opnionated and strict in some places (especially concerning things like vsync) and completely undefined in other areas where standardization is essential (access control).
