I'm actually not sure what this is trying to document is generally useful.

Well at least the goal was to give the user something to build their package around. Maybe it's the documentation style I prefer but when I try out a packaging system the first thing I look for is a runnable example. I'm sure there would be some other things you would have to add in to make the thing work for your application but something that is usable with what most people are doing for the language. With the pip generator thing it is a new different tool while at least my approach was to use what is off the shelf in python itself (setuptools)
