This is tricky - GNOME Shell is a system component of GNOME, and
dependencies on it aren't limited to gnome-session - I also, for
example, see uses of GNOME SHell D-Bus interfaces in
gnome-control-center and gnome-settings-daemon.

I am right now running Flashback session without GNOME Shell. gnome-settings-daemon and gnome-control-center works without it. So at least for now I don't see problem here.

(Do global keybindings work without GNOME Shell running? I thought they
relied on GNOME Shell for that for now.)

Probably not, but that is other problem that I will have to deal with.

 

My opinion is that the Fllashback cannot increase the maintenance load
of GNOME ... there's a reason we wanted to get rid of fallback mode.

It is not my intention. I attached example.patch for gnome-session. Then we need patch for gnome-shell to export EndSessionDialog interface on org.gnome.SessionManager.EndSessionDialog not on org.gnome.Shell. It does not look like it would increase the maintenance load, but would allow Flashback session to show that dialog without using org.gnome.Shell.
