Personally I think this is a solution looking for a problem.

Murray,
I don't think I'm squashing such an idea (standardization is usually
beneficial). I'm more asking, IF we standardize what benefits do we
expect given that many large ISPs do provide much of the feedback
(just
not in a standardized format)?
[So that's what that button does.]
Right, and I believe the goal is an optimization that reduces retries
that are doomed to fail. The question you could probably answer from
your perspective is whether or not those retries are a problem for
you,
either as a sender that provides queueing services for customers, or
as
a receiver that periodically temp-fails for resource reasons.
Standardizing the reply increases the likelihood that clients will
adhere. But if the current setup isn't a pain point for you or
others,
then that suggests there's not really a problem here worth solving.
