Hello,
The current package guide for cargo gives you only the git index, with
the HTTP Index stabilized being used as default for crates.io and being
better for most use-cases.
However, it's not documented that gitea supports the sparse spec, and it
does not require the _crates-index git repo for the sparse api.
I personally think we should push users to use the sparse instead of the
git repository. (Even let users disable crates-index repos if they only
want to use sparse)
