~~Oh yes, seems reasonable, I can play songs using `pw-play` without system bus (dbus service). The session started using `dbus-run-session` seems to be utilized to connect to pipewire (I guess?).~~

~~(Also confirmed by restarting wireplumber and pipewire when dbus was down, to make sure sink/source nodes aren't just cached)~~

No, it seems like it connects to pipewire by dynamically linking with shared libpipewire library, and exposed headers only. I still don't get the use of dbus here...
