True you could do it with your foot. . .but if you eliminate the throttle body, you can very likely accelerate under leaner mixes that eliminate hydrocarbons. If you can do that you can dump the cat altogether and swap in for injection of water up front or something else(ammonia, urea, sometimes water) in back.
I can accelerate at 2000 rpm and very slight depression of the throttle. . .With the same amount of fuel, alot more air and alot less pumping I can accelerate more. So either you can have faster acceleration at the same mpg or you can get same acceleration and greater mpg.
Then a good driver can get lean burn, less emissions and less fuel all the time when otherwise a good driver can only get lean burn under very low acceleration.
