I thought about that too, but how would it be any different than the torque from a single fixed cog? In fact, a fixed cog (with a lockring) would stress the hub threads in both directions alternately, unlike a freewheel. Well, okay, maybe a multi speed freewheel would stress the threads when the chain is on the small cog, but not a single speed.
