RE: NETCONF Notifications: Consensus Points

Randy, Don't hold back :-).

I agree that in a high-delay environment that this would not be ideal -
however, in a secure environment where you want to limit notifications
or in a high-traffic/high-use environment, then it might make sense.
Also, I did not indicate whether this was a synchronized ACK or ACKs
could be batched or what the timing requirements were - just that this
was one use by the sender of an ACK from the receiver.
