One problem not mentioned on that thread is the stress you will put on the throttle body shaft without a throttle stop.
You have some power in your legs and the leverage you gain from the pedal can tweek the throttle body shaft, linkage, bushings, cable brackets, ect with a few stomps to the floor (all common knowledge to anyone that works with carbs and throttlebodys that seems to be overlooked here, or at least failed to be mentioned for the newbies) Already mentioned but less costly to repair is pulling the end off the cable, stretching, ect which some people have reported in your link.
A throttle stop is cheap insurance...cheaper than a throttle body, and it's not very fun sitting on the side of the road with a broken cable.
just my 2 cents.....now I am broke
