Adding MORE technology is NOT the answer!!
A piece of technology will require power - and you must have the ability to cut power to it for safety reasons - so what would be the point of it being there in the first place?
If something were to deny certain actions to a pilot, again it MUST have an override function - for safety reasons - because equipment can fail, and cannot possibly be designed to take ALL possible scenarios into account. (Even an almighty Airbus can be overridden, albeit not easily!) - and if the system can be overridden by a pilot intent on malfeasance - again, WHAT IS THE POINT OF IT BEING THERE?
Folks, look at what we have here - a piece of 'technology' (the flight deck door), albeit mostly mechanical, installed in good faith for good reasons, that COULDN'T be overridden (from outside the flight deck, at least) - and look at the result......
