It's called a debate. I make my suggestion, others tell me why it wouldn't work, and I rebut their arguments.

That being said, you do raise good points about staff availability. I don't know how many ground staffers there are hanging around at a given moment. Perhaps they could be diverted to meet a remotely docked flight, and perhaps they're too busy. Certain airports I know have the spare apron space and others might not. I would imagine they could take a bus off the UAX route to the G Concourse (or whatever the analogous remote terminal is at your airport of choice) and send it to a remote stand without too much disruption. It just seems to me that the airlines could and should develop a system to remotely deplane an aircraft off the tarmac if it will be delayed for a significant period of time.
