This makes sense. My suggestion is, in `tree-sitter.el`:

    (defvar tree-sitter-major-mode-language-alist
      '((c-mode . c)
        ;; And other major modes that Emacs includes, or are well-known.
        (c++-mode . cpp)
        (javascript-mode . javascript)
        (python-mode . python))
      "Alist that maps major modes to tree-sitter language names.")

For other major modes, it's up to the mode writers to add entries to that list,
similar to what they do with `auto-mode-alist`.
