That's exactly what I'm complaining about. Dnf is no improvement over yum at 
all, zif would bring real advantages through the simple fact that it's 
native code, not Python. Native C code is faster, requires less memory and 
is less likely to break when the system is broken (and thus more likely to 
be usable to repair it). Zif also interoperates much better with PackageKit 
(on which our package management UIs, gnome-packagekit and Apper, are 
based), being implemented in the same language by the same primary developer 
and designed with PackageKit in mind (whereas yum happily breaks APIs used 
by PackageKit, see e.g. the repo.str() case; apparently, you don't even test 
your changes with PackageKit!).
