Here I think we have the heart of the debate -- some might ask:

When replacing a cart-and-horse with an automobile, should one  
continue to demand features like "drives with reins", "eats hay",  
"gets bored and wanders off if not tied down", and "leaves horse- 
muffins in yard"? (That's "simulation")

Or is it acceptable to suggest that one should concentrate on the  
"mission-critical" functions, like "can be driven to town to buy  
groceries"? (That's "delivers effective results")

Either way, we have a tendency in this discussion to develop  
requirements that are far more like: "Must be powered by a  
quadrupedic propulsion unit that processes hay by grinding it between  
teeth-like protrusions, fermenting it in a retaining vessel  
containing enzymes and cellulose-digesting bacteria, passing the  
remainder through ten meters of semipermeable tubing that places the  
resulting simple hydrocarbons into solution in a water-based media,  
circulating the water-based media through the motor system of the  
propulsion unit, and extracting the energy in the motor system by use  
of insulin-oxygen reduction of the simple hydrocarbons". (That's  
"specifying mechanism")
