Yeah, I am still waiting for bug reports and feature requests for that ;-)
The only thing where PK falls short is for advanced package managers
like Synaptic on Debian, because it doesn't support features like
holding packages etc. But it was never designed for that. (although to
my suprise someone recently submitted a patch to PK to allow
downgrading of packages)

It would require the distributor or upstream vendor to ship the
metadata[1]. If upstream projects do that, everyone has the required
information, and getting the packages
(e.g. via libappstream-qt) is as simple as
Database::componentById("samba")->packageNames()
AppStream was not only designed for applications, but also to fetch
metadata about any software component. E.g. it is already used for
input-methods, fonts and firmware.

Finding places where KDE software could benefit from it would also be
quite a challenge (it's not documented, and lots of software silently
works around missing components).
