I think lots of Python projects reason this way: Python 3 transition
is the right time to break backwards compatibility in our
library/framework. It's understandable.

Unfortunately this means that for people adjusting their code, they
won't just have to deal with the large Python 3 transition, but also
with lots of their frameworks and libraries making
backwards-incompatible changes. That's unfortunate, as that means any
automatic conversion strategy using the py2to3 script won't be
possible, and there won't be any way to keep libraries in transition
working in both Python 2 and 3 for a while (which is Guido's plan), as
their dependencies don't support it.
