In many American airports, non-gate operations use these blue ramps instead of using aircraft stairs.
Like the ones we have a KIAH.
Additionally, they offer a gate valet service where cargo is loaded into the plane's cargo bay and then handed to passengers on a cart when they deboard the aircraft, removing the need for baggage claim. It would be nice to see this replicated by GSX.
I'm sorry but, I don't think it's really feasible adding each and every passenger with the required animation to grab a bag from a cart. There is a reason why there's only one type of guy handling baggage in GSX, and it's because that animation is very complex.
