This is not the bogey that some make it out to be. Assuming 13 LD3 for max passenger load baggage, space left in the rear hold will take 3 LD6 and 1 LD3 for a volume of about 31.5 m^3. The bigger door would allow 2 96x125 pallets plus 1 LD3 for a total of 27.5m^3. So in terms of space ( volume) there is no disadvantage with the smaller door.
