I believe that Walter has stated that it's on purpose that package be non-
virtual. I know that Andrei thinks that, since he's said as much when the
topic has come up. And from discussions on the matter, I believe that it's
fairly clear that the current behavior is going to stay.
Regardless, the docs clearly need to be fixed.
