In the last mentour pilot livestream, they showed the simulator and both engines, and there's a little graphic near the cutoffs showing engine state and performance. Also, in _this_ livestream as soon as the report was released, Ben mentions in response to a question that if you cut off the engine, a lot of electrical systems are going to face power cuts, so there will be alarms blaring all over the cockpit. So, yes. There are many channels of information here.
