Comment:
I was too ignorant to realize the complex name of the dbus-session file is just the machine-id-0.
~/.dbus/session-bus/$(cat /var/lib/dbus/machine-id)-0.  Since we know what the filename will be, we could simply (if KDE) source this file at login to set $DBUS_SESSION_BUS_ADDRESS.  I leave it to maintainers to ponder whether this is a good idea, and if so, should it happen automatically or be manually done by the user within scripts in the ~/ directory.
