This is Mr. Fart's Favorite Colors all over again. Our "vetting" process is not any more useful than the billion-dollar metal detector you can skip with a TSA Precheck. It arguably does not deter the most dangerous attacks even slightly. What happens when a mentally-ill pilot locks their copilot out of the cockpit? Well, we write off a crowd of passengers and then "vet" the next jet as a safe vehicle.
AI will be the same way. These "safety" measures are performative and do not even slightly address the actual threat surface of the technology. Arguably, it cannot even be done.
