These cameras will eventually be enabled plus they're pointing at your face. This becomes especially important when facial recognition software gets to the point that it can, with high probability, capture your mood. If you look angry or aggressive then you are a risk to a safe flight. It might get to the point where you're escorted from the plane before it takes off due to you looking mad because you couldn't find an overhead bin. An extension of this would be for air marshals to Taser you inflight before you can causes an incident, all because you look drunk or look mad due to sneezing giving you a red face.
