'5' is a rounded, rather than exact, figure.

  and Python 2.7 was extended an additional 5 years.

Think of it this way.  In April 2015, after almost 5 years, support was 
extended for about 5 years, (primarily for build and security issues) to 
sometime in 2020, left intentionally vague.  Based on more information, 
we recently specified the first day in 2020.  Backporting of normal 
bugfixes is already very selective, and the selectivity may increase.

I agree that it is not clear that we actually meant 'final release on or 
soon after 2020 Jan 1".  In other words, no substantive patches of any 
kind after that date.
