I tend to agree that it has a lot to do with marketing, however, not all drivers have the same equipment so some folks may rely on those setup options in their ESC. Unless you're highly skilled (the actual phrase I was going to use may not be permitted on the open forums) and can modulate precise throttle control then most drivers, including myself, usually dial in some throttle exponent to take the edge off the power delivery. I may adjust the ESC's brake setting so that it doesn't immediately lock up the wheels when you barely flick reverse but other than that I don't mess with the ESC settings.
