I would like to push a release of Debian Policy but I want to include the patches in the following two bugs. If you are a DD, please consider reviewing and seconding the patches in these bugs so that I can do that.
debian-policy: virtual packages: dbus-session-bus, dbus-default-session-bus
Please firmly deprecate vendor-specific series files (the patch simply implements a ctte decision)
EDIT 2018/xii/23: these are both now seconded – thanks gregor!
