It's still way too early but I think it will turn out to be something intentional. It'll more than likely take years to find out.
Possible,but highly unlikely. After 9/11 the FAA issued Special Federal Aviation Regulation (SFAR) 92-2. This required modifying transport category aircraft such as the 777 to prevent unauthorized persons entry into the flight deck. I have seen and used these doors many times and can testify to their strength.
Even when performing en-route inspections ( riding on the flight deck jump seat), I can say that all flight crews I have ridden with have emphasized more than once about me not opening the flight deck door inflight no matter what. The air carrier has procedures to let the flight crew know who wants entry - usually flight attendants,before ever unlocking the door.
