Actually, DBusMenu is an upstream KDE feature. You may recall it was
originally a joint Ubuntu/KDE development. We're at KDE SC 4.11 RC1 right
now, so it's too late to do anything upstream KDE in 4.11 and the Plasma
Workspace is feature frozen after 4.11 so that upstream can focus on Plasma 2
(that will use Qt5 and KDE Frameworks). So we're several release cycles away
from being able to do anything upstream.

How does this impact support in applications? For Qt/KDE apps (due to the
integration in Qt4) it just works. There's no need to patch individual
applications. Is this true for QMenuMode? Is it for Qt4 and Qt5? What's the
upstream plan for it?

AIUI, currently unity-gtk-module conflicts appmenu-gtk, so they can't both be
installed together. That would have to be fixed since many users have both
Kubuntu and Ubuntu installed and I think we want to support that.
Also, the gtk/gtk3 patches that supported appmenu-gtk have been dropped, so
even if we brought the package back, it wouldn't build. Can those be added
Also keeping it now, just to drop it for the LTS doesn't really help much
since the Plasma Desktop will still be using DBusMenu and we'd just have to
drop it then.
