There’s also create-rust-app_cli/template-plugin-dev/.cargo/admin/dist, 8MB of compiled artefacts, which looks like it doesn’t belong in version control either.
For best results, please remove these files from the repository, including all its history (git-filter-branch or whatever). Then the whole repository would be under a couple of megabytes, and much more palatable.
(When you’re on the other side of the world from where the repository is being served, downloading that 42MB repository can take several minutes rather than the 10 seconds I might hope for based on my typical download speeds.)
