In particular, when building a flake lock file, inputs like 'nixpkgs' are now downloaded only once. Previously, it would fetch https://api.github.com/repos/<owner>/<repo>/tarball/<ref> and then later https://api.github.com/repos/<owner>/<repo>/tarball/<rev>, even though they produce the same result. Git and GitHub now also share a cache that maps revs to a store path and other info.
