Not really: Elisp-only solution has a few benefits:

1. portability
2. it adapts itself automatically to langauges which can be parsed by
Emacs modes.
3. maybe speed (C might be faster, but with Elisp you don't have to
start a process - this might require some measurement, though).

4. Exactly, a good way to learn/teach something about how Emacs (and its
language modes) work.
