I do drops or hoods downhill. If I want to slow down a bit, I'll go to the hoods and let the wind catch my chest & slow me down.
I wouldn't count on warnings too much. I'm really sure it's a fairly rare problem, but I'd rather take no risk.

As I see it the problem would be on a very fast downhill (like a mile-long 8% for example) where you put a lot of pressure on your hands and may come in need of braking efficiently. My hands feel more securely tight around the handlebar and my fingers more powerful for braking when I'm down on the drops. No slippage possible.

I agree about straightening up to catch the wind more and slow down, though. But I wouldn't risk moving my hands while I'm zooming down at 50 km/h or more.
