As far as I see PEP 420 (implicit namespace packages) is supported by
Python >=3.3 only, so I’m not sure the packages would work even if we
disabled 'sanity-check, do they? Either way, I’m in favor of removing
broken Python 2 packages.

Depending on undocumented setuptools behavior should imo be avoided and
– for top_level.txt – phased out if possible.

Cheers,
Lars
