Obree did some work on this when he fancied the Merckx hour record (eventually he decided this position was unsustainable for an hour)
Honestly, it's tough to think you could come up with a lot more slippery position in drops, but the practicality of it (If I'm remembering correctly it required a custom bike with a long TT, very short drops - and obviously as soon as you sat up closer to a normal track position it would probably look terrible) probably makes up a large part of why it is an odd sight.
