I don't see why you'd assume MyObject doesn't have rich methods and doesn't protect its invariants.

Sorry maybe I'm missing something the purpose of this and your original comment, can you elaborate?

I didn't think there was really any model type classes in this post; save the undefined MyObject. I'm not saying that classes with behavior are bad, I meant more as if it's implementing an interface, then the consumers can work with the interface, rather than the concrete. This, at least in my opinion, is a better high level design, and makes it easier on consumers/callers to understand a system, rather than getting bogged down in the details of implementation.
