Hosting tree-sitter pre-built language definitions on ELPA?

[Yuan Fu]

Tree-sitter needs language definitions to parse different languages. These 
language definitions come in the form of dynamic libraries. We can’t bundle 
them with Emacs since their version must match that of tree-sitter library, and 
we don’t bundle the tree-sitter library; also they are machine-dependent.

I wonder if we can host pre-built language definitions for languages we provide 
tree-sitter support OOTB on ELPA, so users can easily download them?
