That wouldn't solve the main issue, which is the [non-negative] amount of work in porting existing Py2 codebases. Besides, 3to2 (which does exist but isn't maintained) and 2to3 are both bad ideas. They miss edge cases, even common ones, and they add even more complexity to the build/test/install process which people already find hard.
