I'm not sure this means anything :) Importing a module automatically
entails running its top-level code (that's the only way it can create
functions, classes, etc.).

However, I agree that in the default site.py, we could stop calling
main() at the top-level and instead call it from the importing code.

Are there many of them? And usually, you would take the original site.py
and modify it a little. Starting from scratch sounds crazy.

Well, ideally, these modules should stop importing external libraries
implicitly. Give them a dedicated function for that instead, that the
user can call if they want to.
