I don't agree that this is cleanest. I made a mistake by introducing
the recipe namespace. New recipes I write won't use this. "Flat is
better than nested." Also, for smaller projects, I'm avoiding
intermediate src directories to avoid the annoying nesting. (I'm a
little uneasy about this, but can't see a serious downside other than
setup being importable in develop mode.)

IMO, the only needed hygiene is the top-level namespace. (Maybe a
huge organization would need sub namespaces, but we don't.)

I would love to see this. I haven't been able to think of a good way
to do it reliably, especially considering the important use case of
develop eggs, which want to run directly from a checkout.
Again, for smaller project, the pain can be mitigated by skipping the
src directory and avoiding nested namespaces.
