Why do you think that RowState+RowOps does not
achieve the "fate vs state" claim? Seems to me
this claim is basically realized.

As you noted, a list of POTENTIAL and sometimes CONFLICTING rowops
requirements was posted a few weeks ago along with a request
for comments. So far very few, if any, comments have been received.
The current rowops draft reflects a subset of those requirements.
In sum, this draft attempts to make do with current PDUs and structures,
provide reasonable (if not optimal) packing efficiency, separate fate
from state :-), not impact current VACM/AgentX configurations (though
AgentX itself MAY have to evolve), allow a reasonable and incremental
transition strategy, provide opportunities to simplify NMS appl and SNMP
agent instrumentation coding efforts (though not necessarily master
or other core code modules), provide some new features (bulk head/tail,
extended errors, three-phase SETs), etc..
I agree with you that more discussion is needed regarding requirements.
This draft simply serves as a backdrop from which we can compare
ideas. For example, Steve and Sandra have proposed an interesting new
of aggregating rowOps in existing PDUs. At this point we need more
list discussion/consensus before we can make wise choices and produce
a more ideal draft.
