Perhaps because everyone is using a bridle rope nowadays?
A bridle is much easier to use and much cheaper. Even most cruisers have switched to a bridle rope AFAIK. The downside is you need a stiff boom and a strong kicker (16:1).
The beauty of the bridle system is that leech tension remains the same on every course. Leech tension is solely controlled by the kicker. Having a bridle rope is like having the traveler to the luff at all times, even after a tack. See WIT for rigging details: (http://www.wayfarer-international.org/WIT/WITindex1.html)
