Most 152 pilots don't do anything with those pedals other than taxi.

I assume you're joking when you say that. My guess is that if a 152
lost its rudder, it would be completely uncontrollable. Having a
rudder and not using it is a whole different ball game from having it
fall off. Even if it's just hanging on the back of the plane unloved
and unused, it's contributing to lateral stability.
