After carefully reading dbus-launch(1), I understand now the fall back

Fom man :
<You can always avoid autolaunch by manually setting DBUS_SESSION_BUS_ADDRESS>

I have this drop-in config as recommanded by my distro (Archlinux) wiki[0]:

/etc/systemd/system/user at .service.d/dbus.conf

I start systemd --user as described in wiki.
