> Yes, it's true but on the other hand, a KDE user doesn't need and doesn't want all GNOME specific packages just to have the dock.

That KDE-only user doesn't need /usr/share/gnome-session/. Splitting off
cairo-doc.session to a package she doesn't need to install may be just
the right thing for her.

Who said that it should be? I was thinking of doing it the other way around:
make it (cairo-dock-gnome-integration, or whatever it will be called)
require the core cairo-dock packages. People who want to use Cairo-Dock with
GNOME would ask for this package only, and everything else they need would
follow. Ditto for cairo-dock-kde-integration, cairo-dock-xfce4-integration,
etc. as appropriate.

I've also been thinking about the Enhances header, but as that is a reverse
Suggests rather than a reverse Recommends I don't think it will help much
in this case. (Maybe dpkg needs to grow conditional dependencies, that are
activated only if a combination of several packages is installed; but I
haven't done the math to see if this could actually be made to work, and
in any case it would have to be filed as a wishlist bug against dpkg first.)
