The setuptools package was added to allow definition of namespaces using the now outdated (and discouraged from use) pkg_resources-style. The code here, for a long while now, uses a try/except (`ImportError`) protection around the setuptools code, and falls back to the more encoraged pkgutil-style. Removing this library won't affect any current workflow, and in the case of setuptools not found, it'll actually use a more modern (and encouraged) flow.
