My gut reaction was to say: "The same reason there are no after-market turbo chargers for those little gas scooters that seem to be so popular lately." ...as a backhand reference to the fact that IDE dtill does not support concurrent outstanding I/O via tagged command queueing. But the fact is that there are IDE RAID controllers, even though I personally think that a server will have much more need of concurrency than a desktop.
