CAFE is of huge importance to OEMs, if they can get .01mpg from running springs that are barely good enough for a stock cam new, then that is exactly what they do.
Maybe in the 70s you could get away with keeping stock springs with a cam upgrade but that has not been an option for a few decades now.
