I don't know. You tell me! ;)
I didn't design this thing and I have gnome-shell so everything works for me.

I don't know. I'm looking up things as we go here....

The signalling between gnome-session (manager) and gnome-shell
seems to be handled via an abstraction in gnome-session/gsm-shell.c
where the outgoing calls are made and replies interpretted and converted
to gsm-internal glib signals.

Usually the dbus api is described in a .xml file, but in gnome-shells
case it seems it has been embedded in the javascript code.
eg. https://git.gnome.org/browse/gnome-shell/tree/js/ui/endSessionDialog.js#n48
