Willing to contribute or just take this over

So it looks like this was never really finished and hasn't been touched in a couple of years. I'm willing to take it over if y'all are no longer interested.

If you are interested I'll just make PR's, but I'm not sure anyone is even looking at this repo anymore.

The issue names no file, test, entry point, or concrete change. First check whether the repository is still maintained and clarify the intended scope with maintainers; there is no defined completion criterion yet.
