Where do people on HN meet these devs who are willing to do this sort of thing, and get anxious about being 3 months behind the latest and greatest?

In my world, they were given 9 years to switch to Python 3 even if you write off 3.0 and 3.1 as premature, and they still missed by years, and loudly complained afterwards.

And they still can't be bothered to learn what a `pyproject.toml` is, let alone actually use it for its intended purpose. One of the most popular third-party Python libraries (Requests), which is under stewardship by the PSF, which uses only Python code, had its "build" (no compilation - purely a matter of writing metadata, shuffling some files around and zipping it up) broken by the removal of years-old functionality in Setuptools that they weren't even actually remotely reliant upon. Twice, in the last year.
