I hope so. It would only look off until people got used to it. There's nothing special about movies running at 24 fps; we're just used to seeing them that way so they look awkward at any other speed.
My guess is it's similar to the same commitment a lot of directors have towards actual film versus digital recordings. Some film junkies get excited over things being shot in/for black and white. So I can see why 24 fps might matter to them, but I certainly don't need things to run at 24 fps.
It looks like most the thread disagrees though. *Shrugs*
