I believe that we actually did discuss an aura that negates flying within X spaces back near the beginning of this design. It ended up not gaining too much traction because we want the effects of the Destructible Object to be clearly conveyed by the structure itself, much like how the gameplay effects of the official terrain were clearly linked to its appearance. There are also some rules problems with stopping flying within an aura, though that wasn't the main reason we settled on the current direction.
