I've noticed the other day that a FGW Portsmouth - Cardiff service stopped at two stations between Southampton Central and Fareham - Swanwick and another one (I can't remember which), so it COULD have happened. It depends how many stations it would have needed to stop at in addition I guess, one or two then it's no big deal IMO but if there are four plus then you risk passengers missing their connections which could cause issues if it was a late night service.
It is frustrating though, a while ago during the morning peak, my train got cancelled and then 10 or so minutes later, all four carriages sailed past the platform leaving everyone to squeeze on an already very well loaded two carriage sprinter!
