No it is not a matter of testing. It never worked in the first place, so
it is an imcomplete implementation, not a bug.

We should probably restore the original method that was responsible for
unloading known packages, and put it into the 4.5 deprecated package so
we will remember to delete it whenever the replacement functionality has
been fully implemented and tested.
