Psychic guards are still in. I expected that, but I'm still petitioning for their removal.
There is no good reason for the guards to instantly know you have escaped Fort Joy, and no good reason to prevent the player from returning to the prison after they escape.
Saying "The guards keep tabs on the prisoners" is a bullshit excuse which makes no sense. It's bullshit because the guards clearly do not keep a close eye on the prisoners, nor do they give a rats ass what happens to the prisoners. Slaughter Griff and his whole kitchen? The guard who walks through there doesn't care. Go hang out on the beach near where you start? Guards don't care. Teleport to a waypoint outside the shrine for 3 seconds then teleport back in - KILL ON SIGHT.
