Preamble: Shaman does support PackageKit as its main backend.

That said, in KDE history we always tried to circumvent those standards 
providing our own API for a variety of reasons. Some examples are HAL->Solid, 
PolicyKit->KAuth, GStreamer->Phonon and so on.

Now, for each of those three cases the decision was right and paid back 
greatly the additional effort. KDE was not affected by the switch HAL-
>DeviceKit->USomething, neither by PolicyKit->polkit-1, and with Phonon we're 
able to provide a wide range of backends.

The whole point of not using PackageKit's API (beware: PackageKit's API only) 
directly is to provide our developers a KDEish API, guaranteed to be BC, in a 
similar fashion with what we've done with SC 4 until today. Everything I 
mentioned before is a fd.o standard as well, but we built a wrapper around 
nevertheless.

So the whole point is: we surely mean to use PackageKit and its Qt library as 
a backend, like we've done with polkit & friends, but we'd better provide our 
own API to avoid changing the workflow of our developers and have more control 
over the whole situation.

my 2 cents.
