Right, but in this case, a field converter would need to create the whole hierarchy of ProductOptions and Coupons just to be able to switch one product option value. If the matcher would be used instead, the change is very specific to that field, like a json morpher before klaxon actually initiates the class. A field converter is actually a custom class instantiator in this case and not just a field conveter... but I agree the concept might be confusing...
