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".
