I'm going to hold the line on MUST.  The protocol doesn't make any sense if you get (valid) duplicates and don't discard them.  Given that you have to track what you are acknowledging, then the only additional cost is the threshold, which is nearly zero.  It can even *be* zero if you use the minimum value from what you are tracking.

What do you gain by having anything less than MUST?  That is, other than the potential for crazy non-determinism.
