That reminds me -- Yuan, have you seen my PR to tree-sitter-langs, Hacky
support for treesit in Emacs core [2]?

It uses tree-sitter-langs' groundwork for fetching grammars and
packaging highlighting queries, but uses treesit instead of the
tree-sitter dynamic module.

Enabling highlighting is just M-x treesit-langs-hl-mode in major-modes
that tree-sitter-langs supports.
