Is that an autogenerated tarball? I am under the impression that usage
of those is banned in GNU Guix, and that there's a lint pass for it.
What do you use these autogenerated tarballs for? Is the 'ls-remote'
command not enough to replace the version and hash? GNU Guix uses
shallow clones (AIUI) to save bandwidth, do you need this to generate
the hash? I encourage you use the same shallow clone mechanism here, so
it's more generic and not specific to Sourcehut.

What do you think about that last idea of matching versions in tags
with ANY separator and ANY suffix and prefix? That should work fine,
right? I can't think of a case where it wouldnt, but please do share
one if you do.

Thanks!!
