Yes, I did. The pipewire properly reports 'unconnected' state, but
nothing stops user from selecting the unconnected device / verb.

No. The jack (and the pipewire status) reports unconnected.

Have you tried switching to the unconnected sink? Starting the
pipewire when the previously selected sink is now disconnected?

Is the changing of the JACK names the only change in the UCM? compared
to your previous version?

I've used the following topology, fom the topology repo / x13s-dp branch
