Is there any rule to only include tree-sitter packages which are mentioned in the tree-sitter neovim readme?

I opened a PR to add the parser to nvim-treesitter, so it will be integrated in the plugin soon enough.

I dont think so, other programs use treesitter such as atom/helix/semantic/emacs/zed etc

[SuperSandro2000]

Hmmm, I also don't think that it is a good sign that the repository is just a week old and has 0 stars on GitHub. I don't think we should add all our own and very tiny projects to nixpkgs. An overlay is a perfect place for such a package until it is majored a bit more.

@SuperSandro2000 it has been added to nvim-treesitter, if that changes your opinion on whether it is worthy to be in nixpkgs.
