If the new clause is only for delays, then we can't extend use of the
clause to cover extra processing steps.  If the label is for more
general use, then we can.

That's OK, but now I'm wondering if the syntax should allow a list of
states rather than just one

Received: blah blah STATE DOWNCODED-TO-7,MODERATED blah blah

I don't think we're talking about this kind of metadata here.  Really this is 
meant to talk about a delay introduced while waiting for something to happen, 
usually operator intervention of some kind (quarantine, list moderation).  An 
automatic step like downcoding or (for another example) virus scrubbing only 
introduces a compute delay and a bit of I/O, not an enforced 
usually-human-caused delay like the other cases.
