Windows users who don't use a third-party distro like Enthought, generally download the python.org installer. At the moment, that doesn't give them a "pip" command. So if they want to install any third party package, they have to start by installing pip. The instructions for that are reasonably clear, but non-trivial, largely because tools like curl are not commonly available on Windows, and by default running a Python script may not do what you expect. Rather than try to fix these problems (which are hard) the intent is to have the pip command installed by the python.org installer. [...] I can't speak for Linux distros or OSX users, but for Windows I do believe that this is a significant improvement, and worth the (IMO, negligible) risk involved in adding this to a maintenance release.

I'm not an OS X user, and probably most people on this list use macports or something similar, which essentially puts them in the same boat as the linux users...and there's a section in the PEP about that (that's where the message about installing pip if you run pip and the distro didn't include it with python is supposed to come from).

For OS X users not using something like macports, I'm pretty sure they are going to be in a similar boat to the Windows users, with just a touch of added confusion coming from the fact that an older version of Python is already installed. But the instructions they will find on the web for installing package X (once this change hits the field) will be to install the newest version of 2.7 (or 3) using the python.org installer, and then they will have the pip command and can go from there.
