I downvoted this because it seems to be missing a very obvious point - that the reason why an early filter would be good is because we've already passed it. If we hadn't passed it, then of course we want the filter as late as possible.

On the other hand, I notice that this post has 15 upvotes. So I am wondering whether I have missed anything - generally posts that are this flawed do not get upvoted this much. I read through the comments and thought about this post a bit more, but I still came to the conclusion that this post is incredibly flawed.
