Wrong. The separate branches approach allows you to have a clean Python 3 codebase without crippling the Python 2 codebase.

There may be warts in a single codebase (you usually can't have something for nothing), but it's not necessarily crippled when running in 2.x.

Of course two branches allow you to have a no-compromise approach for the code style, but you might pay for that in time spent doing merges etc.

Note that 2to3 is actually helpful when you choose the dual branches approach, and it isn't a serial dependency in that case. (see https://bitbucket.org/pitrou/t3k/)

Yes, 2to3 is very useful when doing an initial porting exercise. I've used it just once in each port I've done. It also works well for a single codebase approach, only I just follow its advice rather than letting it do the conversion automatically.
