Come on, that's not what happened. IIRC Jim Fulton and Philip Eby
worked with Martin to make easy_install / zc.buildout calls on PyPI
efficient. Then I started the PEP later, but because I wanted to set
up an "official ring" of mirrors.

I am the one to blame because I didn't update that part of the PEP yet
consequently. But the PEP doesn't really address the protocol to be
used to browse PyPI. It's just informative. This is a de-facto
standard for years now (you use it everytime you install something
using pip or easy_install), and it was discussed in the Mailing Lists
back then when it was created. It didn't land in a PEP back then, like
other stuff don't.

So nothing was decided in private.

Now the push stuff could be great to have maybe, but I agree with
Martin that we should first setup the mirrors then learn from there.
(For the story, I've proposed a push stuff at first when we started to
discuss this PEP, but I eventually agreed that this was not the most
important thing to have our first version of a mirror ring).
