Dear John,
Until they fixed the storm drains in the City Park, I dunked my bottom bracket and derailleur a few times every summer after heavy rains. They finally got tired of hauling dead cars out of the hundred-foot puddle and pumping all the water into the nearby pond, so things are better now.
Until they fine-tuned the discharge from the Pueblo Dam, I dunked my derailleur (but not bottom bracket) for about a week every summer, just past the "Caution: Path May Be Under Water" sign.
Today and yesterday I went early enough to avoid the thunderstorms and didn't even get soaked.
Cheers,
Carl Fogel

Does cyclocross count? If so, yes.
And I say it counts.
BTW, the brains of the outfit is in the front derailer.

Thanks for that info.
Imagine the electronics in a continuous 30 kph blast of water drops. That is worse than immersion.
