Yes, that's working code, on window managers that honour it.  But I 
don't actually recommend it for the purposes you wanted it for.

Would however be vaguely okay for people who don't want to reach for the 
mouse to use the relevant window manager menu.  If it were to be 
included in emacs it would make more sense to treat it as a frame 
parameter at the elisp api level, similar to the handling of several 
other similar existing parameters, i.e. so one could write

(set-frame-parameter frame 'always-on-top t)

(I think this was what Stefan was saying, pretty much)
