Interlocks and relays can and do fail. So I imagine there would be a lot of engineering development work and risk matrix work required before it became practical. Is it worth the expense? I don't know. Airlines have refused to wear the development and ongoing maintenance cost for things far less complicated than that!
Totally missing the point. They are talking about using them for taxi only. I.e. Clear the runway, after landing checklist then shutdown the engines. So there's no reason for the motors to spin up at all until the aircraft is already at a complete stop and off the runway.
