While he doesn't explicitly say so, I got the distinct impression reading his recent blog post that he supports one source, not forked sources.

I've ported a fair bit of code, both pure-Python and C extensions, both libraries and applications. For successful library ports to Python 3 that need to remain Python 2 compatible, I would almost always recommend a single source, common dialect, no-2to3 approach. There may be exceptions, but this strategy has proven effective over and over. I generally find I don't need six but it does provide some nice conveniences that can be helpful. With something like tox running your test suite, it doesn't even have to be painful to maintain.

Cheers, -Barry
