Interesting. If there are two objects with fields a, b and c, and one object initializes them to 1, 2 and 3, while another - to 1, 2 and 4. Does it make sense to derive the second object from the first? Or the other way around? I thought business can be viewed as a specialized service. But both approaches are possible, so the choice of "default" says about our preferences.
