What's the compelling reason for message by message copy directives?
The reason for per-message [copied] flag is to optimize for 
the common case where callout server does not modify the 
data. OPES processor will often keep a copy anyway, for many 
reasons. There is no need to send the same data back and 
forth; one direction is enough in this case.
The reasons for copying commitment or a similar mechanism is 
to optimize for the common case where the callout server 
wants to get out of the loop because it does not expect 
any/further modifications.
