I thought about that, but then I realized that the acceleration is going to be (more or less) equal and opposite for take-off and landing, so it's more about which one you want first, no?
The angle of descent is of about 3 degrees, that's far less than the angle at which the aircraft is taking off. Thus the rear facing passengers would be facing down quite steeply on takeoff, and thus likely to vomit the airport lounge food they just had :)
