On wily the dbus package first offers dbus-user-session (user bus) over dbus-x11 (session bus)[1], just as in debian unstable. So I guess there is still some transitioning to be done for upgrades, but unless the installer does something manually you should end up with user sessions by default. Moreover, I think under kdbus session bus is not supported (I can't find a link though).

I don't see a problem with everyone that uses this protocol shipping the policy file and let distributors handle shipping just one version via Conflicts/internal coordination. -- Saludos, Felipe Sateler
