What do we think @AaronBallman ?  I think the diagnostic column is as best effort as we are going to get, so I'm OK with this as-is.  WE could perhaps improve that, but I don't think doing that here is worth the effort.

I'll approve, but I want to make sure Aaron has a chance to say otherwise before merging.
