I suggest to rather list good PEP-implementing modules/packages 
on some "pypa" PEP-independent administered page and reference that page
prominently.  Given that we have a mixed py27/py3 python ecosystem and
will do so for some more years, and given that things are still moving,
focusing on adding such to the stdlib is wasted effort IMHO.
