Good comments from you all. Thanks!

The specific problem we are attempting to solve is interactions between 
MONITOR message generation and MPF. With the changes we made during the 
Console Restructure, MONITOR messages can be produced without a console 
requesting them. You can request that the messages not be queued to a 
console for display purposes (but will be queued to EMCS consoles for 
automation purposes) and you can request that the messages not be logged. 
All of this was done to allow customers whose automation require the 
messages to receive the messages but not have the messages -- optionally -- 
go anywhere else. The problem is that if a customer requests that the 
messages not be logged but puts an entry for the message in MPF, MPF 
undoes the no logging. The simple solution is to remove the message entry 
from MPF, but perhaps the customer wanted to drive an MPF exit, and then 
would be unable to do so.

There is a more general question and that is how should we be handling 
messages that are being generated solely for automation and being solely 
consumed by automation? The MONITOR messages are but the tip of the 
iceberg in this regard. We have had requests for ways of specifying on 
commands that the command response message is to be returned to the 
console (typically an EMCS automation console) but is not to be logged. 

>From the comments I've seen so far, whatever we do must be optional.
