Having DNF in C is desire of many users. If you could notice the thread from Courtney Pacheco, she did investigation [1] to minimize the Fedora image (which is bigger than in other distros). The DNF will probably be taken out of that image. Mostly because of the Python requirement. By dropping Python requirement, it could speed up the the process start-up (no need to load Python libs then). That is also the reason why PK does not call DNF Python API from C and rather have a special library in C instead. > I can think of many reasons for doing this, but it would probably be > better coming from the development team doing the work.

Gradually DNF is moving more code into C but still a lot of code is in Python and plugins are written in Python too. Having rewritten DNF into C would take a few years while maintaining the UX compatibility and still support Python API for plugins. The main message was to inform the consumers of hawkey to prepare their apps for the libhif change.
