[Distutils] Rejecting PEP 439: implicit pip bootstrapping

Donald's PEP 453 for explicit pip bootstrapping (by inclusion of a
"getpip" module in the standard library, automatically executed during
installation by the CPython binary installers) is now available on

Accordingly, I am now formally rejecting the implicit bootstrapping
proposal that Richard put together for PEP 439. The explicit
bootstrapping proposal in PEP 453 should provide a more reliable
experience, both on initial installation and when upgrading both pip
and CPython.

Discussions on PEP 453 will likely be split - here on distutils-sig to
ensure the proposal is acceptable to the pip developers, and on
python-dev to ensure it is acceptable to the CPython team.

As a proposal with a direct impact on CPython, final pronouncement on
PEP 453 will take place on python-dev rather than here.
