Isn't it entirely possible -- through liberal use of 'six' and 'from
future...' -- to write code that will operate correctly with both
Python 2 and Python 3? I thought that, e.g., OpenStack was pursuing
exactly that strategy.
Sure, you still need your target Python 3 environment to have the
appropriate supporting modules, but that seems like a different issue.
Environments runnning Python 2 should continue to Just Work.

The difference here is the span of versions that need to be supported.
OpenStack is only trying to support 2.7-3.X and the gulf between 2.4 and
2.7 is actually quite broad. It is likely possible, but it will be a
very large amount of work and would add dependencies to both runtimes.
Because "no setup" is such a huge part of what makes ansible attractive,
I doubt adding that dependency would be viable.
