I think that would be good data to have in the Guix Data Service.

I'm not sure quite how this data would fit in, I guess it would be
similar to the data for nar files, but more limited to fixed output
derivations.

I think the first step towards this would be to experiment with fetching
data from the Software Heritage API. Do you know how you'd fetch data
about the output from a fixed output derivation (like harfbuzz)?
