Even if I was for it, they'd never actually implement it. I will always be in favor of game devs and communities looking for ways to stop cheaters, but automated anticheat software has proven to not be the way to do it in a large mmorpg environment such as this.

Anticheat software tends to have a better impact on games with smaller player groups in a single game instance, like FPS games or Arena pvp games; where these programs can have a tighter focus on what to look for with far fewer machines/clients it has to scan.

In the end, human/manual intervention just works better for FFXIV; it's not perfect, but it's much better then the hellscape of something like XIGNCODE3 or nProtect Gameguard.
