I'm not sure how much extra testing Intamin is gonna want for the switch track. Hagrid's has it, sure, but this is also a much faster acceleration and speed.
A switch track failure would be similarly disastrous whether the ride is going 40mph or 80mph. Pantheon being significantly faster than Hagrid doesn’t really affect the technology they’re using for the element or mean they have to test it more or less to prove it works.
