[Distutils] PEP 439 and pip bootstrap updated

[Richard Jones]

The point of PEP 439 is that the current situation of "but first do
this" for any given 3rd-party package installation was a bad thing and
we desire to move away from it. The PEP therefore proposes to allow
"just do this" to eventually become the narrative. The direction this
conversation is heading is removing that very significant primary
benefit, and I'm not convinced there's any point to the PEP in that
case.
