Not really, because pk-application therefore takes 0.5 seconds to change
the current selected package (because it fetches the description, or
worse, runs get-depends). Any user interaction would ideally not take
more that 0.1 seconds to give a response.

But then, maybe that's just a design flaw in the way pk-application uses
PackageKit?
