Dozens of emails back and forth between all authors in the 1995 time frame.
All lost to history now...

Great.  The intent was to make sure that no author interpreted an AA:
message as a need to PUSH multiple retries to deliver and AA message.  No,
in that sense the AA: message is not a message, but is a kind of a human NAK

Great idea.  Good addition..

AMEN.  Yep, That is why these 5 rules were intended to make sure that no one
could forget an leave these AA messages locked-loaded-and ready to fire
FOREVER!  Ugh...
