I think the short answer, as always, is: getting pip into the stdlib
would require a tremendous amount of work that some would have to want
to do before it could happen. IIUC, the current direction is
something like "get a packaging standard into the stdlib that people
can build tools on top of" c.f. distutils/packaging.
 And that work is not always technical. A lot of the hard work is
getting people to agree on things.
