 It was clear to me, despite your mistaking _NET_CURRENT_DESKTOP and 
_NET_WM_DESKTOP once.

 As I read the spec, it allows this already (and it works with KDE). It says 
in description of _NET_WM_DESKTOP that 0xFFFFFFFF is a special value, and 
that to change desktop one has to send the message with 'new_desktop'. It 
doesn't explicitly allow or disallow it in the message, but until now I 
wouldn't have expected anybody to wonder about it. If you think it needs to 
be said explicitly, feel free to change it.
