I'd much rather they cancel the flight then strand me in a plane for 2 hours. At least if they cancel it, I have a chance at re-booking on another flight.
Time will tell, but I don't think its just the airlines that should be involved in the fix. The airports themselves need to make it less of an issue for a plane to return to a gate. I'm also sure there are FAA rules that get involved in the problem too....
