I'm creating a 3.20-prime branch for gnome-kit, and it has the following 'extra' ebuilds in it that aren't listed in the package-set:

gnome-extra/cinnamon-control-center
gnome-extra/cinnamon-screensaver
app-accessibility/espeak
net-misc/networkmanager-l2tp
sys-power/upower
dev-util/gtk-doc-am
dev-python/pygobject
dev-python/pygtk
app-editors/latexila
app-editors/gedit-plugins
dev-python/pyatspi
gnome-extra/cinnamon-settings-daemon
app-editors/gedit

Note that there are several dev-python ebuilds, which normally live in python-kit. the question is whether it is safe to remove these from gnome-kit or do we need them forked here?
