when user package new software to NixOS, they need git clone this package then git commit, gh pr create. If a mirror is available, it can speed up git clone.
从我个人的理解来看，用镜像站的 git 版本做开发，然后给上游提交 PR 是非常怪异的事情，并且存在因为同步延迟导致 PR 出问题的可能。如果实际需求是包含所有历史的仓库太大，需要减小 clone 下来的仓库的大小，可以参考 https://github.blog/2020-12-21-get-up-to-speed-with-partial-clone-and-shallow-clone/ 来做，或者使用 GitHub Codespaces。

This has no real use for end users. Developers are supposed to handle GitHub connectivity themselves, particularly when the goal is to submit PRs on GitHub.
nixpkgs.git 大概是有非提交 PR 的场景的——在需要 pin 住 nixpkgs 版本的时候。
根据 https://api.github.com/repos/NixOS/nixpkgs 的报告，仓库大小为 4028389 KB ~= 4G，TUNA 的大小报告是 3.7G（https://mirrorz.org/list/nixpkgs.git）
考虑到 git 带来的额外 IO 与 CPU 压力，在 nix 实现了 blobless git clone 之后会考虑同步，相关 issue 参见：https://github.com/NixOS/nix/issues/6111
