I am not sure about this. cpychecker is more beneficial to CPython extension devs than to CPython devs, since it is almost impossible to let the cpychecker learn the most updated internal function definitions without handwritten attributes or seeing the whole function definitions. So it depends on the extension maintainer. I am observing this pattern that popular libraries are gradually upgrading. 3.9 and 3.10 is definitely the current mainstream. Saying so, I think 3.9 is fine for now, but it will be outdated after 2 to 3 years. Best, Steven
