I do think Rick has some exceptional points to make, specifically that the future pool of avalable engines is only going to get more and more sophisticated and complex; outlawing modern design and technology for its' own sake may not be the best course. Sooner or later the supply of "old guard" equipment (like my trusty ol' dinosaur, then the next generation) will dwindle, and then what?
