Prosecuting people for doing that won't actually change anything, because very few people in emergency situations are actually thinking clearly enough to even consider laws in the first place. Compare to airline seat belts: the reason they always have that demonstration at the start of the flight about them is because there have been cases where people literally forgot how the seatbelt worked in an emergency situation, didn't have the mental coherency available to figure it out again, and kept trying to push at the side of it where the latch release would be in a car. A better legal approach would be to place limits on carry-on luggage in the first place, so that the physical possibility of delaying evacuations with it is removed.
