I'm just confused because I see some new definitions and I see test changes, but I don't see the producer of the value changing anywhere so it isn't clear to me what the actual difference in behaviour is. I'm guessing the new `ScalarEnumerationTraits` specializations are the cause, but is the value different in the actual DXContainer or is it just a display thing with the YAML?
