I see it exactly vice versa. A normal new language feature, you *cannot*
get early from PyPI, e.g. if it's a syntax extension (e.g. the with
statement). OTOH, *this* particular feature you can easily get from
PyPI - just download and run the PIP installer.

I'm sure there is something that can be done about it. What operating
system are people using who have difficulties to set this all up?

I see that pip doesn't have a Windows installer on PyPI. That looks
like the real culprit to me. I'd be willing to work with you to
provide one (that ideally bundles all dependencies).

The backporting is the main stumbling block. Otherwise, I'm in favor
of the PEP.
