Ross, I suppose that could be a consideration however on newer aircraft not all slide packs are stowed inside the cabin. On the 777-300 The LR3 slides are in the wing/body fairing and thus could not deploy into the cabin. However, then you have the potential for there to be damage to that area rendering the slide ramp U/S.
The same goes for the MLR3 and the upper deck slides on the A380. The MLR3 are in the wing/body fairing and the upper deck slides deploy from hatches below the doors. I guess they have the room for this in the A380, but to do it on all doors of a single deck widebody probably would present its own space issues (eg cargo hold in the way etc)
Apologies for the slight drift, maybe we can take this to Tech....
