Review comment:
       I wrote these notes and code months ago, shelved it and nearly 
forgotten, and today I remembered it and submitted it.  The TODO here was kind 
of a note-to-self that can be removed.  I'd welcome anyone's thoughts on this 
though.  There appears, to me, to be overlap in scope between metrics and 
"status" type requests.  Years ago I thought Metrics was just numbers, but 
lately I've seen it can have all sorts of strings and basically completely 
compete with "status".
