I guess you'd have to try to convince the X people to change it. It would
be better to find a solution that doesn't involve changing it, or maybe
add a KDE/Gnome extension (we've already added "priorities" so apps can be
started in a certain order). If someone was serious about making SM work
well they'd probably maintain a joint KDE/Gnome SM spec in addition to the
gnome-session implementation, to describe any changes.

Perhaps the SM spec people expected clients to track this info, and maybe
register an rsh or ssh restart command if necessary? This is just a guess.

The other problem is that even if WMs were doing things right, few apps
set the class, name, and role hints properly to allow them to work.
