I miss setuptools in this list.  For the latest 26.0.0 there is a wheel, 
a tar.gz and a zip, and that has been the case for a while.

https://bootstrap.pypa.io/ez_setup.py still explicitly looks for a zip 
file.  Occasionally the package maintainers forget this and an issue is 
raised, though apparently this has been automated to avoid such a error:
https://github.com/pypa/setuptools/issues/549

That said, I occasionally have erroneously uploaded a zip file when a 
tarball for that same version was already there, or the other way 
around.  They contained potentially different code: either I forgot to 
do a 'git pull' before releasing, or the previous uploader forgot to do 
a 'git push'.  Allowing only one sdist would have prevented this.  But 
really this is our own mistake.

I think I have always discovered this and removed the new distribution 
and uploaded a full new version to avoid problems.  I don't recognize 
any packages in the list.
