gnome-session will have a fallback for this in 3.14. Initially we
assumed that gnome-session would go away totally, but seems even with
systemd --user you'll still have a gnome-session around. It just does
less in case of systemd.
Note that I'm just talking about gnome-session. GNOME not under systemd
does have it fair share of reduced functionality. Further, in my
experience it was *way* more stable to either go for full systemd or
always rely on the reduced functionality. The runtime detection of "is
systemd running as PID 1" was IMO not very stable (and that wasn't just
GNOME components, others as well). Though that was under Mageia and
later on Gentoo provided various patches to improve it (but no idea how
good the current state is or if we regressed anywhere).
