Classes with virtuals are used polymorphically (why have virtuals
otherwise?), so they need virtual destructors to be deleted
properly. Unless they are never deleted using objects of those two
classes -- but why have the interface in the first place if that's the
case?
This is binary incompatible change. It was agreed upon in the mailing
list.
