Badchad seems to be under the impression that everyone who shoots USPSA is looking to go to nationals or be #1 in their division.
I shoot USPSA (production and L10) in order to get what I feel is good training time with my holster & pistol, doing mag changes, target acquisition, etc. Being a MA resident unless the mag was made before our ban, it's a felony to possess, so most people I know with newer firearms can only have 10 round mags. Bringing those people out to shoot production gives them more experience with their everyday pistol and at least a shot at being competitive if that's what they're looking for.
There's no good reason to change it.
