Yes, I didn't see the backend capability to do better, so I figured we might as well use the big hammer unless it's shown that we can profitably carve out exceptions to the rule. 
If you think it's worth trying harder, I can take a look...although I'm not sure exactly where/how we'd do something with this pattern.
