$ guix import go --goproxy="https://pkg.go.dev" gopkg.in/yaml.v2
guix import: warning: Failed to import package "gopkg.in/yaml.v2".
reason: "https://pkg.go.dev/gopkg.in/yaml.v2/@v/list" could not be
fetched: HTTP error 400 ("Bad Request").
This package and its dependencies won't be imported.
guix import: error: failed to download meta-data for module 'gopkg.in/yaml.v2'.

The package exists and the URL looks right:
