I like unit tests, and I would happily adopt a CI system if my project included non-Python code and had to build multiple wheels. But formatting code properly in my editor is second nature by now; the functions I write are typically so short that it'd be hard to do anything a linter would object to; and type-checking doesn't just introduce busy-work, it works against part of the reason I'm using Python in the first place. I actively don't want to tell people not to call my code with a perfectly compatible type just because I hadn't considered it as within the range of possible compatible types.
