The thing is that our previous implementation used yum as a backend.
We've covered most of its functionality and *reinstall* is one of its
commands. Now we'd like to have PackageKit-based implementation
supporting all the features of the former one.

I see it as a problem of backend to solve the dependencies and security
gotchas. I can imagine that several supported ones don't have this
functionality since it's nontrivial to implement (I haven't checked).
Well this doesn't have to be mandatory feature for each backend.

You are right. This is a fairly common use case though. And it's not
just my experience and needs. Check out our bugzilla for number of bugs
related to reinstall [1] and downgrade [2].
