Why do we have an augmentConversion interface for only STATUS?

[matthchr]

The SystemData property only exists on the Status type. All of the other properties on the Spec are primitives or genruntime types.

So I think this is correct, the only complex child type is SystemData and it only exists on status, so that's the only complex child we have augmentConversionFor interfaces for?
