Largely, as has been explained ad nauseum, because GAA doesn't work for situations set up for a different approach. This seems obvious, but here we are.
Well, to be honest it's not like we had to strain to find such situations. For example, Determining what your character knows is a pretty universal situation. It's a big deal that GAA (as a philosophy) doesn't have a mechanic to do that.
