I find it confusing to have parameters an implementation has no use for. The "MAY choose to expose as read-only" is actually a bit awkward in this case, since ideally, users can add entries to the object (in which case it's weird to have read-only parameters set by the implementation). It's not disallowed -- just weird. I would like to mark them optional to implement. I don't think this would impact the YANG model (because the YANG model doesn't deal with the mandatory/optional to implement aspects of the spec)?
