Will the relevant projects actually support only 2.X and 3.4/5+? If
they expect to or have to support 3.2 or 3.3, then this change isn't
actually going to help them much. If they will only support versions
of Python 3 containing this change, then it may well be worth
considering the impact of delaying it till 3.5.
