 A pull request for which you do not need to contact us in advance is the addition of a new language to Jupytext. In principle that should be easy - you would only have to:
 - document the language extension and comment by adding one line to `_SCRIPT_EXTENSIONS` in `jupytext/languages.py`.
 - add the language to `docs/languages.md`
