Batfink, it's highly unlikely that the cargo will slam into the forward parts of the aircraft at cruising altitude. Considering that you are neither climbing or descending, and your speed is equalized, the chances of cargo "sliding" forward in steady flight are slim. Even if it did, the amount of force required wouldn't be enough in steady flight.
Most likely the cargo would slam into the nose at lower altitudes when you are descending and braking. Either way, Boeing took into thought the fact that it can happen, and did something about it. Airbus didn't seem to care. Although it's highly unlikely to happen, it can. And the chances of surviving a lost nose are much greater when the pilots are alive and still inside the cockpit.
