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.
One of the innovations since the 1980s when X was designed are shared libraries, so you can have libweston and wlroots now https://github.com/swaywm/wlroots
While the first X11 release was in 1987, the fundamental architecture was designed already since 1984, and this architecture includes a heavyweight server that implements things that in most other window systems are done client-side.
