Python 3 check explicitly tells the reader that 2to3 should only be used in Python 3. Otherwise everybody need to guess when this *2to3 tools are triggered. As for me, I see no technical limitations why *2to3 can not be run by Python 2 (PyPy, RPython or whatever). Maybe I don't have Python3, but want to build my package for Python 3. In ideal world it is possible. This is not an ideal world and 2to3 is not good enough to convert files without further intervention and testing.

It is if you design your code to be converted by 2to3 and do regular testing of the result.
