Oh I agree, and the funny thing is I heard second hand is that the city's water treatment people still would prefer you just throw away your scraps (or better, compost). It does end up being a little useful on occasion, though, and it also creates a whirlpool that drains the sink faster.

That said, if I need the voltage from that breaker to power something else, I'd forsake it in a heartbeat. We already rerouted the garbage compactor to help power the heat pump we put in.
