> I was really happy with building tree-sitter not requiring any Rust just yet... Do you think this is strictly necessary?

I think the CLI is part and parcel of tree-sitter as a whole, so currently we have an incomplete package in the repos. I say that based on [this explanation](https://tree-sitter.github.io/tree-sitter/implementation) from its homepage.

Yeah, we could have something like `tree-sitter-cli_package()` but, as you said, Rust demands fine-tuning manual installation, so it would be a bad choice maintainability-wise. I can in fact use the `cargo` build style for the CLI and then run the appropriate `make` command in `post_build`/`post_install` as needed, what do you think?
