They do split the grounds at T2 when staffing permits. In the morning, they bounce back and forth between 121.8 and 124.25 constantly for the South Field. Hopefully in a few years I'll be in a position to try my hand at it, but there is only so much you can do. The SFO configuration was never meant to have this many airplanes. It'll be even worse when the new T1 opens along with Terminal "H" which will be adjacent to terminal G with several more international gates. It'll be game over if the airport seriously turns the United MOC on the Northwest side of the field into a remote terminal.
Until construction is over, SFO is about to lose all widebody remote parking in the terminal area except for by the G-terminal. That means several wide-body tows per day upstream from the A-term to any other random part of the airfield. With housing prices so crazy out here, people never seem to stay long at the contract vendors that re-position airplanes. The voices never seem to last very long, I'm sure they go to United or Delta as soon as they get the chance to work for a "real" company and have some quality of life. I see something hilarious at least once or twice per week. At SFO, even at the ramp level, you get so used to people screwing up and almost hitting each other that it doesn't phase you, you just work around it. That's probably why both Air Canada screw ups were unreported for a few days, just another movement at SFO. Nobody died.
