Speaking for third-party library authors, almost all cross-version code that does anything remotely close to a network is 2.7 and 3.3+. Requests dropped 3.2 support basically as soon as we could once 3.3’s unicode literals were restored, and since then I haven’t written anything that targets 3.2. It’s just too frustrating.
And while I’m shoving my oar in, I’ve never seen anyone be happy with using “from __future__ import unicode_literals”. As others in this thread have said, it just points a loaded gun at your foot and lets you wait for it to go off.
