This should help if there are issues fetching from the source repository.

“;for (guix build download-nar)” rather.

Otherwise LGTM, thanks!

I copied this comment from (guix git-download), and I think it makes
sense. There shouldn't be any need from (guix build download-nar) to
have guile-json and guile-gnutls, it even specifically avoids using
https for this reason.

I think why these extra inputs is indeed just to import (guix swh as
it's required by (guix build download).

Great, I've pushed this to tex-team-next now as I'm hoping this will
help fix ci.guix.gnu.org building tex-team-next.
