As someone who ported WebOb and other stuff built on top of it to Python 3 without using "from future import unicodeliterals", I'm kinda sad that to be using best practice I'll have to go back and flip the polarity on everything.

Eh? If you don't need unicodeliterals, what's the problem? Porting the WebOb code sucked. It's only about 5K lines of code but the porting effort took me about 80 hours. Some of the problem is certainly my own idiocy, but some of it is just because straddling code across Python 2 and Python 3 currently requires that you change lots and lots of code for suspect benefit.

Could this manual work be cut down if there was a version of 2to3 that
targeted the subset of the language that is compatible with both 2 and 3?
That would seem to avoid most of the drawbacks to the current 2to3
approach.
