Emacs does have a package to use tree-sitter [0]. I think emacs-lsp is aware of this highlighting backend and performs pretty well.

(semantic highlighting is pretty slow for C++ with font-lock, with tree-sitter it's a breeze :))

Wait what? You mean to tell me that Emacs LSP already uses tree-sitter?
