Right, so just to make sure we're on the same page:
 - guix size pipewire before this patch:
https://paste.debian.net/hidden/57a05080/
 - guix size pipewire after this patch:
https://paste.debian.net/hidden/cbb93545/
 - diff: https://paste.debian.net/hidden/3cb51fbd/

Surprisingly there isn't that much of an increase (~5MiB). That's
because most of the new dependencies were already pulled in by
existing dependencies.
For example, PulseAudio was pulling libsndfile &
webrtc-audio-processing. Bluez was pulling readline. I traced one
OpenSSL use back to a ffmpeg plugin dependency (rav1e's rust-cargo-c,
it's also used by other things but the Graphviz graph is too big to
generate a visualization).

This leaves us with only these new dependencies (see diff):
libfdk-2.0.1            75.2     3.5   0.4%
libusb-1.0.24           72.1     0.4   0.0%
lilv-0.24.12            74.0     0.3   0.0%
