Well, in an ideal world, you don't need filters at all. In reality, they are useful because certain bosses and encounters don't conform to the normal logic any sort of artificially intelligence would apply to the given circumstances. The filters are indeed a way of segregating certain behavior, but only really if you are forcefully applying logic to a situation that does not conform to the normal behavioral standards, which is why "automation" of them is impossible. By their definition, if they could be automated, then they are not needed.
