Book learning, as well as any other kind of learning, is a nice algorithmic exercise. It takes time to develope and fine tuning. Disabling it is telling the programmer "you wasted your spare time". As for getting won positions out of book... isn't that what a book is finally meant to do, after all? Don't human players try to do this all the time? When I played in tournaments, I got a couple of full points out of book. I studied games of my opponents, found weaknesses in their openings and analyzed them with my brothers (computers were too weak back then). Nice memories of the past...
