WirePlumber: device unexpectedly disappears

I'm half-way through a (what I thought was going to be) simple WirePipe setup. I want a config-driven setup, hence I'm avoiding GUIs.

Devices involved:
  - laptop
  - external monitor (has integrated speakers)
  - wired headphones with microphone

Desired behavior:
  - never use external monitor speakers
  - use laptop speakers and mic
  - use headphones speakers and mic if plugged

Actual behavior:
  - if headphones are plugged: headphones speakers and mic are used
  - if headphones are not plugged
    - no audio output is defined
    - pwctl status does not list the laptop speakers
    - pw-cli ls Node does not list the laptop speakers
    - restarting pipewire and/or wireplumber systemd services did not help either

More context:
  - I've managed to use this GNOME extension to manually select and use the laptop speakers, but then if I plug the headphones the laptop speakers are not automatically selected
  - if I delete ~/.local/state/wireplumber, heaphones are automatically selected when plugged, but when unplugged the laptop speakers disappear again

Config files:
