I very much agree that Python 3 should be the default, however, IMO
there's not much point supporting Python 2 and not providing the needed
command line tools. To me, either you support Py2 fully, or you just
don't support it at all. YMMV I guess.

Well, it may sometimes be needed. For example, let's say Stretch is
released, and at some point, Buster gets Python 3.6. Some packages may
support only that, and then you may need X-Python3-Version: >= 3.6. But
if we have already 3.4, and you're declaring "I'm supporting only >=
3.2", then there is no point.
