Yeah, but is it supposed to be avoided to apply new features in Python 3.x to Python 2.x? Sorry if there's already a consensus.

The feature set of every Pythonx.y version is frozen with the release of CPython x.y.0. Thereafter, each x.y.1+ release only gets bug fixes. Note that the new audioop feature in 3.4.0 was not backported to the subsequent 3.3.? release.

Python 2.7 is generally no exception, but because of its extra long maintenance and projected life, a few security features have been backported.
