I'm sure the latest GP bikes (certainly Rossi's Ohlins) have compression and rebound damping split that way - I think I read it somewhere. It stops the oil overheating and breaking up during a race as it's not put under as much stress.

It'll be a cost thing on the Dark though, and I reckon on anything less that full whack on a track the best option is compression and rebound on each fork.
