In addition to what Richard wrote I have to admit that I did plan to
provide interaction with X session managers for the x11 backend of
GNUstep for years. It doesn't look to hard to do, but is rather boring
and actualy nobody has ever asked for it in all these years.
Perhaps you are interested to implement thsi yourself for GNUstep. If
not, you could try to lobby me into doing it.
