All the MAF sensor does is to measure the density of the air entering the engine.
Indeed - my line of thinking being that it might be a system that when cruising takes into account engine load when calculating throttle position input - to smooth things out going up a hill. The other reason I was wondering is that someone did put up a diagram of a US aftermarket cruise kit and there were more connectors to the engine ECU that I would have expected - however they weren't labeled with their function - only the pin used.
