Patches uploaded to the cpython tracker are public and can be and 
sometimes are used by other people without or before being officially 
applied.  Separate packages are fine too.

Yes.  There are two competing proposals (PEPs) for improvement waiting 
for a decision from an appointed judge.

This is not a security issue, so enhancements cannot go in 2.7.

This was determined to be an internet security fix.

Some core developers have backported new modules they wrote as external 
packages.  Thank you for your comments.
