I think the generic form of this exercise -- for the purpose of justifying the work -- is to describe intended use and explore with potential implementers the likelihood that they are interested in that use (or any other use) of this possible work.

Yup, me too.  I'd also be curious how the most common MTAs (sendmail,
postfix, exchange, etc) react to reply codes they've never seen before.
They /should/ handle 'em gracefully, but there could be surprises.

I don't recall seeing any code in sendmail that reacts to other than the first 
digit of the SMTP reply code itself, and nothing that looks at the enhanced 
status code.  No idea about other MTAs.

This might create a need though.
