I agree. On one hand I can understand the need to shrink code, focus on the core functionality etc..., but on the other hand X has e.g. "xset" and "xbindkeys" which can be used for all X-desktops (or "Window Managers" or however they're called). With wayland each single desktop environment has to re-implement all that functionality => looks like wasted effort to me - the modularity (from the point of view of functionality) of X is lost in Wayland.
