Comment:
Note that the issue with `dbus-run-session` isn't that it makes a bus specific to `_pipewire`, but that it creates a *random* bus that *no other process*---including pipewire---will know about. Using `dbus-run-session` in, say, your xinitrc works as expected because a random bus is created and then all processes inherit an environment variable telling them where to find the bus.

If any process needs to communicate with wireplumber via this dbus session, dbus will have to be configured (as will all who wish to talk to it) to use a well-known socket. If nothing actually talks to wireplumber on this bus, why does wireplumber require it?
