What I want to do is to indicate that a window should initially be
maximised (similar to how one can indicate that it should initially be
minimised through WM_HINTS). I haven't seen any other way but to
manually set _NET_WM_STATE. But if that's ok then it should solve my
problem.

Sorry, I thought that was a GNOME specific list. And since the wm spec
had the XDG signature on it I thought this was the correct forum for it. :)
