Yes please.
I genuinely don't understand how anyone can think _/_/_/ is more comfortable than _| _| _|, particularly at mealtimes.
I don;t think it will happen though. So in its absence, I would settle for a ban on reclining during mealtimes, and encouragement for people to ask, or at least warn before they recline, and to do so slowly.
I remember one easyJet flight where I flinched, such was the ferocity of the seatback flinging itself it my face 15 seconds after rotation. Some people just can't be trusted with the responsibility of something as simple as a reclining seat.
