[issue19728] PEP 453: enable pip by default in the binary installers

Martin v. Löwis added the comment: I agree with Nick; this is really a minor issue and we can resolve it here in the tracker. I missed the place in the PEP where it said that the option should be checked, since it mentions changes to the installers twice, and in "implementation strategy", it d

Nick Coghlan added the comment: As far as updating the PEP goes, it's a rare PEP indeed that is implemented exactly according to spec - the integration process almost always uncovers details that don't quite work out the way we thought they would. For minor issues, we usually handle such changes
