Maybe and I don't want to assert that the way that it is designed is wrong, given my limited experience. That said, I can remember one other time that I hit an issue like this and it left an impression that still gives me pause, whenever I want to use comparative metamethods. 

Presumably, the limitation guards against super-ugly code that's hard to debug. One wonders if it's harder to debug wonky type comparisons or something buried in your code that fails every 1 in 2-10 times, but only inside of busted[1]?
