I couldn't find any mention of OpenStack in these pages.

OpenStack is definitely driving at python3 compatibility, but work is
ongoing. I understand it will simply pull in Python 2, and that's o-k.
But it's worth noting that the subject of this mail is very alarming. It
is not that Python 2.7 won't be included with 16.04.. just that it won't
be on the default install.
