It's also worth noting that pip has no mechanism for installing an
updated stdlib module, as everything goes into site-packages, and the
stdlib takes precedence over site-packages unless you get into
sys.path hacking abominations like setuptools uses (or at least used
to use, I don't know if it still does). So as things stand,
independent patch releases of stdlib modules would need to be manually
copied into place.

Allowing users to override the stdlib opens up a different can of
worms - not necessarily one that we couldn't resolve, but IIRC, it was
always a deliberate policy that overriding the stdlib wasn't possible
(that's why backports have names like unittest2...)
