Does suse use systemd to manage the pulseaudio user service? If not,
what component does remove $XDG_RUNTIME_DIR? It would seem logical that
the same component would terminate services that break if their sockets
are removed.

What about fedora? I somehow would expect fedora to be eager to adopt
the socket activation feature in pulseaudio that has been available for
a long time already.

If you're using pulseaudio under systemd, it seems weird if all user
services don't get terminated on logout.

Maybe the gnome session management doesn't remove $XDG_RUNTIME_DIR?
