Yes you are correct, this has more to do with outgoing services.

In my prototype I take care of this, but yes it would be more of an
advantage if systemd provided defaults. The different network managers
could sync, and service providers would know where to plan to place
services.

It also may be interesting to setup faculties for systemd to subscribe
to supported network managers, and handle the state machine to
activate the targets. systemd could subscribe to the specific dbus
signals indicating state change, and react accordingly. We could start
with connman and gnome network manager. It might be interesting?

With network state being important along with the types of connection,
it could be very powerful and even enhance security. NFC, WIFI, WIMAX,
3G, BT, WIRE, will most certainly have there own special out going
services.
