Agreed, the specification is much to vague.

Thats why it is a protocol. The wm would have to treat clients supporting
the protocol differently.
But the problem with making it a WM_PROTOCOL is that it doesn't follow the
documented convention
for WM_PROTOCOLS: 

All the protocols in which a client can volunteer to take part involve the
window manager sending the client a ClientMessage event and the client taking
appropriate action. For details of the contents of the event, see section
4.2.8. In each case, the protocol transactions are initiated by the window
manager. 

 (from ICCCM 4.2.1.7)
