title: Can we replace find_packages with find_namespace_packages in python 3.3 onwards and get rid of the empty init.py files?
body: <p>I have a distribution with multiple package and sub packages. There are many empty <code>__init__.py</code> files used to tell <code>setuptools</code> that the folders are packages.</p>
  <p>In python 3.3 onwards, setuptools supports <code>find_namespace_packages</code>. So is it a good idea to get rid of the empty <code>__init__.py</code> files and replace the find_packages with find_namespace_packages?</p>
