No problem with any of that. Please understand that on the whole, I'm
in favour of the setuptools features. (While I dislike intensely some
of the setuptools "ecosystem", such as easy_install. In fact, one of
my goals in wanting this PEP accepted is to ensure that I can get the
"good bits" of setuptools, without having to buy into the
easy_install, dependency management, automated download infrastructure
that currently goes with it).

"We" in this context denotes the people at the summit. Please remember
that people who weren't there still have an opinion - and it may well
differ. I'm not saying that it *does* differ, just that the view of
the summit should not be viewed as conclusive (unless the way Python
is developed is very different from how I understand it).

And as with any PEP, that's a difficult and thankless task (I got a
taste myself with PEP 302, and that was far easier), so just for the
record, you have my thanks for doing this.

But there *are* issues with setuptools. Some users have mentioned them
on a number of occasions. I've raised a few myself. By all means
introduce the good ideas into the core - but make sure people agree
that the ideas *are* good.
And remember - all I said was that people may react against the
setuptools-style terminology. Not that they dislike the *idea*, just
that they might dislike the way it's presented. After all, one common
complaint with setuptools (and one that I agree with) is that its
documentation is obscure to the point of being hostile.

Thank you. I'll try to make the time to go through the PEP and comment

No, that defines an API, which as stated in the PEP, "allows a
third-party application to use the uninstall function and make sure
it's the only program that can remove a distribution it has previously
installed". It does NOT define a standard uninstall command, to
complement the standard install command.
