Yes, but making a backward step like reintroducing u'' just to make things a tiny little bit sucky doesn't seem to me to be worth it, because then >= 3.3 is different to 3.2 and earlier. Armin's suggestion of an install-time fixer is analogous to running 2to3 after every change, if you're trying to support 3.2 and 3.3+ at the same time, isn't it? You can't just edit-and-test, which to me is the main benefit of a single codebase.
The downsides of a unicode_literals future import are spelled out in the PEP:
http://www.python.org/dev/peps/pep-0414/#rationale-and-goals
But the PEP doesn't address the unicode_literals plus str() approach. That is, the rationale currently makes a false claim. --David
