It took me numerous tests and lots of reading the dbus literature, but
I finally managed what I wanted.

First, I parsed
DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/dbus/user_bus_socket
in my X environment (adding in ~/.xprofile). This way X11 services
have a given dbus adress.
Then I started my dbus user session this way :
ExecStart=/usr/bin/dbus-daemon --config-file=/etc/dbus-1/session.conf
(removed the --nofork --nopidfile --systemd-activation options).

This leaves me with only one dbus session:
157:gabx       961   913  0 11:41 ?        00:00:00
/usr/bin/dbus-daemon --config-file=/etc/dbus-1/session.conf

and this output from systemd-cgls:
