If a person is riding their bicycle in -30C (without the windchill

grease or oil inside the freehub body entirely so that that
lubrication does not freeze and cause the unwanted freewheeling?

My guess is it isn't the oil, it's water that's freezing causing the
problem. It's happened to me in the past. Strangely, leaving it out
works better as the ice is displaced never to return, but if it warms
up, the water pools, and refreezes again. Just my guess.
