Well, all DEs (excepting maybe Xfce?) have members in the work groups that design the wayland protocol extensions, so it can be assumed that people are well aware of what needs to be done.

Wayland has a default implementation called Weston, but I'm not sure that any of its devs cared enough to implement the extensions which are responsible for all the other bits that you mentioned.
