> If you can submit a measurably faster csv implementation to cpython (without breaking existing code of course) I can guarantee it will be welcome whether you’re a first time contributor or not.

I wouldn't be so sure. Search for `site:bugs.python.org "maintenance overhead"` on your favourite search engine.

8 results total, with exactly one entry that’s remotely relevant (i.e. performance related, patch provided) — bpo-21955. You could have just linked that. And this happens to be a patch from a core dev. And it’s not comparable to submitting a performant implementation of a PSL module like csv. You have chosen a pretty convincing example, I don’t know what I’m supposed to be convinced of though.
