I've tried this out in combination with the D-Bus 1.10 update patches.
It's perhaps worth pointing out that user sessions only work in
combination with pam.

I also found that one minor fix was needed in
meta/recipes-core/dbus/dbus_1.10.2.bb. Andrew, Ross, feel free to just
squash that into the pending patch.

But overall it looked good, so I'd love to have this in OE-core.

    dbus_1.10.2.bb: fix path to systemctl
    
    When compiling with systemd, pam and user sessions, the resulting
    /usr/lib/systemd/user/dbus.socket ensures that the right
    DBUS_SESSION_BUS_ADDRESS gets put into the environment when logging
    into the system.
    
    The default configure behavior is to look in the PATH, which picks up
    the tool from the host sysroot. We need to override that so that the
    final location on the target is used instead. This is only relevant at
    the moment when enabling user sessions, but it makes sense to fix the
    value in all cases.
