I think it is a feature for tarballs that have disappeared from upstream
(it sounds a bit crazy, but some projects delete old versions, or move them
to a separate location). Some also modify the tarball without giving it
a new name.

I think it is a bug because usually hydra is slower than upstream.
Using "--no-substitutes" prevents the download of tarballs, but also the
maybe desired download of binaries from hydra.

I would be in favour of downloading tarballs from upstream by default, and,
if it fails, keeping tarball downloads from hydra as a last resort.
