The cockpit door is designed to break open in both directions in case of a decompression. On Airbus aircraft, if a flight deck window blows out the door is designed to pop open inwards, otherwise the cockpit floor comes up and the control cables get taken out (for the rudder and THS on FBW a/c).
The Authorities are doing the right thing by trying to avoid a KJR which results in possibly greater hazards.
