This is funny. You know that window minimization is not in the X11 spec either, right? Its something that X window managers handle internally (just like on Wayland where this is an internal compositor thing).
Of course, desktop apps wanted to interact with minimization (read current state, etc), so the WM authors joined forces to create a spec that allowed this. See how it specs minimization here:
http://standards.freedesktop.org/wm-spec/wm-spec-1.3.html#id...
This is part of the "wm spec", and the thing corresponding to it in Wayland is called "xdg_spec", Both are produced by "xdg" (X Desktop Group) and are optional things that are used by "traditional desktop environments".
It is a good thing that wayland does not enforce the existance of window minimization, because it is not always something that makes sense in all use cases of wayland. For instance in a phone like Jolla.
