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.
