Few days ago, I submitted a patch(https://github.com/python/cpython/pull/4417) which updates2to3 converts `operator.isCallable(obj)` to `isinstance(obj, collections.abc.Callable)`.

This was Serhiy Storchaka’s idea(https://bugs.python.org/issue32046) and I agree with his idea since `callable` is not available in all 3.x versions.

However, some people would like to clarify the policy of 2to3.
That means that 2to3 is compatible with the branch that is currently maintained? or it is converted to specific Python 3.X codes with the specific version of 2to3?
