That's nice, but that's not the question.  The question is whether I can
take qmail or sendmail or any other MTA, use arbitary delivery agent X and
arbitrary submission agent Y, and expect that both X and Y understand the
same format of subaddresses.

The present-day answer is obviously "no."  Is there any way to make the
answer be "yes" other than standardizing the format subaddresses?
