Implementing an Invisibility perk would require an ENORMOUS overhaul in the enemy AI, which is already absurdly complicated. It's not as simple as making the player "invisible", as the enemy can see of the player's metadata. In a very distant parallel universe where the Invisible perk exists, I imagine that Shadow is still completely visible to the player, but the enemy cannot access data such as Shadow's position. The enemy would rely on metadata that determines sound cues to tell what move Shadow is using.
