The obvious question here is: why?

APT is written in C++, not Python, and, while I'm not using it personally (I 
use Fedora, not anything deb-based), AFAIK, the native aptcc backend is 
working fine, so why revive the Python-based one? We have an application in 
C and a library in C++, so why go through Python?

Python backends are actually not that great for PackageKit, and in fact one 
of the reasons Richard started zif is to have a non-Python backend for 
Fedora.
