Security isn't done at the individual gate in Terminal 4 (newest terminal). And actually security screening at the gate is a pain in the ass. Once you're screened you're stuck in a room with no bathrooms (you need to leave and get rescreened). And if your flight changes gates (happened to me), you have to get rescreened all over again.
It is helpful in the sense that bottlenecks don't happen earlier on, but I'm not sure it's that great of an approach.
