However isn't this to some extent reimplementing DSN - which a lot of 
people are currently not doing because the spec is complex and opaque.  
Exim doesn't DSN right now...  I think I will spend time looking at 
this since up to now I have been accepting other peoples comments on 
that RFC

which is the problem with adding mods to SMTP or MTAs - we have to 
carry the people who don't follow the upgrade path.

Definitely.  Can we have a NOT_TODO as well with a list of the things 
and excerpts of the list discussion so that we don't have the same 
discussion set every few months.
