I'd say that's A reason.  The entire MARF WG is somewhat vulnerable to these 
same sentiments.  If such arrangements are a set once and forget it setup then 
perhaps.  OTOH, if these are things that are subject to change (perhaps, for 
example, reporting requirements are different during a particular system 
upgrade rollout) then there is utility is having a standardized set of knobs 
to turn so that software support adjustments without a lot of customization or 
cost.

We absolutely can save this argument for later, so we probably should.  We may 
collectively know more by then.
