This shouldn't be a problem as long as you understand the implications and you are fine with it. Deep object hierarchies can and usually do become a problem. Before you say yes to inheritance you should consider composition (which is what they are doing). The duplication buys you improved encapsulation/compartmentalization and can insulate your application from or ease the pains of refactoring when parent implementations change. Just a thought. Peace.
