Hrm, are you suggesting that the "stateful non-config" be hidden 
directly from the user such that only existing monitor interfaces are 
used to query it's contents?

I'll have to think about that a bit.  Obviously, the existing commands 
would still be authoritative even with a query-state command.  I think 
the only question is whether there's value in making this totally opaque.
