Right now the information from pkg.go.dev is used to populate the package's
  * synopsis
  * description, and
  * license
sections.

As far as I can tell, godocs.io does not have any information about the
package's license... *eventually* we may want to consider writing a
license guesser of our own, as that could potentially be useful across
all of Guix.

As for description, godocs.io seems to collects description information
differently (inferiorly?) than pkg.go.dev. For example, compare:

  https://godocs.io/github.com/mitchellh/go-homedir
  https://pkg.go.dev/github.com/mitchellh/go-homedir

I wonder how complicated it would be to guess at a synopsis/description
ourselves? It may be worth asking the initial committers of the go
importer.
