Well, in order to pull off working the ball off the tee, you've got to be comfortable doing it. I've found that playing a very straight ball flight (if it stays that way) can still be very effective in positioning yourself around a golf course. Instead of fading it around the dogleg, you can take a more aggressive line, but with a straight ball flight. If you miss it a little right with either shot, you're still going to end up in the same place.
Equipment (balls and clubs) are designed to hit the ball with little spin, including sidespin, so the technology is trying to hit it straight, why fight that?
You could always adapt a Bruce Lietzke type philosophy where you only teach your driver how to fade (for example) and if you need to draw it, use your 3 wood.
