At least in the downhill event the courses cary similar prestige to motor racing tracks. There’s no one world record race, each track has its own world record pace. A major redesign to the course would warrant starting a new list of times. I’m not sure if the same hold true for slalom, GS and Super-G. There are more rules about course length and number of gates in those disciplines, but I imagine major race venues would also track their own world record.
