That's not true. 2to3 is well suited for supporting both 2 and 3 from
the same code base, and reduces the number of compromises you have to
make compared to an identical-source approach (more dramatically so
if you also want to support 2.5 or 2.4).

And 2to3 is a good approach to maintaining a common code base.
