Comment:
I think there's no reason to make it configurable, because that is the default system socket path (the clients would need an env var with the custom location otherwise). It's the same in [upstream's systemd unit](https://gitlab.freedesktop.org/pipewire/pipewire/-/blob/master/src/daemon/systemd/system/pipewire.service.in) (`%t` expands to /run I guess)
