The persons who are running PyPI should only edit individual pages in
exceptional situations (illegal content etc.).

I was under the impression that you want to to promote Python3 adoption.
Why don't you contact Logilab and check the rest of the packages manually?

I don't think it is the top priority of PyPI to facilitate generating
automated statistics. Also, anyone can upload a package without any
editorial process.

I don't know enough about the organization of the zope.* hierarchy. Perhaps
some people want to see that e.g. zope.interface is green.

On the whole, I believe that users of zope and plone are already acutely
aware if/when Python3 compatibility will happen. For the rest of Python
users, it would be far more interesting to see a wider variety of

Regarding the lock icon on a red background: Authors who use the
Python::2::Only tag want to be left alone. It is completely beyond
me why someone who once made a package freely available should
have a moral obligation to follow language changes forever.

What are you going to do in 10 years? Leave the Pylons entry with
a lock icon? How about maintaining a "wall of shame" for free
packages written in K&R C or free packages written in FORTRAN 77?

If an author has decided to use the classifier, he already accepts
that his package might get less attention in the future. This isn't
an easy decision, so please respect the intent of the classifier and
remove such packages from your site.
