I think the auto shutdown of engines in flight, in case it senses reverse thrust, is a great design.
The 787 is a replacement for my 767 (currently a pilot on the aircraft) and in 1991 a Lauda Air 767 suffered a failure in one of its thrust reverser and it became activated during cruise. The aircraft was destroyed in flight.
The thrust reversers should not activate during flight (a air/ground sensors prevents that) but as it is a catastrophic failure, having the engine shut down automatically seems like a great fail safe device.
In this case it seems that the 787 engines were reversed before the air/ground sensor had sensed ground and it is a potential problem.
