This sounds like your personal interpretation. I see nothing "pure" in 2to3.

It's "pure" in being optimized for a world where you just stop using Python 2 one day, and start using 3 the next, without any crossover support.

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).

Anyway, if you're supporting both 2 and 3, a common code base offers many attractions, so if it can be done, it will.

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