This is what’s up! Having worked on several medium sized python projects where linting and type checking were introduced late in the game, having them as a first class feature of the package manager will save so much unnecessary pain.

IMO, part of the problem is that people just don’t know that linters or tools like this exist at all. This is the best type of product marketing where the product gets meaningfully better, while educating the users for free.
