That sounds like some a case of a random repo by someone who didn't do anything for public consumption. This is not a norm and I don't think you can judge the Python ecosystem by this case just as one cannot judge the JS world from one rouge package or a package that contains a one liner. I work a lot with both python and javascript and the points you raise just don't seem applicable. Neither are more "stable" than the other. They are what they are - cons and pros and all that.
