Perhaps I'm a bit slow, but how would it not do this if it relies on the
inheritance of a previously non-existent environment variable that needs
to be deleted if a process shall not be killed on session exit?

I still don't understand why this would be the case. I assume what Havoc
wrote is true, i.e. stuff that uses xlib or dbus is already covered. How
is it difficult to let the remaining handful of processes die when the
session exits? We could even let these few register themselves with
gnome-session (or whatever else is applicable) so it could explicitly
kill them on session exit, couldn't we?
