The example here is about downloading github.com-generated tarballs, which we don=E2=80=99t do in Guix for other reasons. The kind of tarballs that Guix packages refer to are not autogenerated; they contain more than what the VCS has. Thus, they=E2=80=99re also more difficult to authenticate if they=E2=80=99re not signed. Thanks for sharing! Ludo=E2=80=99.
