The argument for splitting the category is kinda null tbh. There are only 2 runs completed using the hyperjump strat which is a very impressive strat to pull off in a run. If you split the category it will make those 2 runs look less important, the hyperjump is indeed RTA possible as proven by these 2 runs and if people want to compete for the record or top times in 0 Star they will simply just have to learn the strats required to obtain those times.
The main difference with the camera in the Deluxe version is that it attaches to mario more. So when you jump the camera moves up and down with mario where as the previous versions do not have this feature. The deluxe versions camera can be quite annoying when you are doing speed runs for a long time.
