This would still not be sufficient, AFAICS. The top-level targets will only have relatively few direct dependencies. Let's suppose gnome-session.target has "Requires=mutter.service gnome-settings-daemon.service" and mutter.service then has a "Wants=at-spi2.service". We still want to stop at-spi2.service together with the session. DependenciesPartOf=yes in gnome.target would not achieve that (or it would need to apply transitively, and to Wants= as well, which sounds quite strange). OTOH adding "PartOf=graphical-session.target" to all graphical session specific user services works fine and works with the existing systemd model and dependencies.
