complication it introduces.
I've done a Google code search and there doesn't seem to be much more

The current idiom is not extremely pretty but it works, and it doesn't
seem to cause much trouble. The fact that setuptools proposes a
different idiom from pkgutil's is not due to the idiom itself, but
probably historical reasons: both idioms require a single import and a
single function call, so they are similarly expressive.
The lack-of-prettiness argument is quite underwhelming when there are
so few projects using namespace packages; and this is not something you
see when you only *use* the package, rather than develop it.
