If OS builders (distributions) have chosen to use the per-user bus, this provides two possible modes of operation for compatibility with existing X session startup hooks. A legacy-free system can just upload DISPLAY, XAUTHORITY and possibly DBUS_SESSION_BUS_ADDRESS into dbus-daemon's and systemd's activation environments, similar to http://cgit.freedesktop.org/systemd/systemd/tree/xorg/50-systemd-user.sh installed by systemd (but unlike systemctl, dbus-update-activation-environment works for traditional D-Bus-activated services, not just for systemd services). A system where compatibility is required for environment variables exported by snippets in /etc/X11/xinit/xinitrc.d (in Red Hat derivatives, Gentoo, etc.) or /etc/X11/Xsession.d (Debian derivatives) can upload the entire environment of the X session, minus some selected environment variables which are specific to a login session (notably XDG_SESSION_ID). In Debian, I plan to put the former in a new dbus-user-session package that enables a user-session-centric mode of operation for D-Bus, and the latter in the existing dbus-x11 package, with the intention that dbus-x11 eventually becomes a tool for change-averse setups or goes away entirely.
