Why are the queries not in sync with nvim-treesitter's queries?

[viperML]

In my journey of investigating how tree-sitter works, I've noticed that the queries are duplicated here and at nvim-tresitter repo, and I see that they are not kept in sync.

• https://github.com/nix-community/tree-sitter-nix/tree/master/queries

What is that? Should neovim and other highlight program prefer any of the 2?

The highlights.scm captures are poorly specified by upstream tree-sitter, so most editor plugins do not use parser-provided queries (nvim-treesitter, Helix, emacs-tree-sitter, Zed).

There has been some discussion about fixing this, which appears to mostly be in this nvim-treesitter issue: nvim-treesitter/nvim-treesitter#3944
