As far as I'm aware (and having reviewed the release notes for 3.1, 3.2
and 3.3 as well as the planned features for 3.4), Unicode literals are
the only feature to have been added that was intended to make it easier
to support Python 2 and 3 in the same codebase.

Given that no code currently on pu uses Unicode literals, I don't see a
reason to specify a minimum version of Python 3 since we're already
restricting ourselves to features in 2.6.
