Both Trevino and Watson wrote/said that you ought to try to find a level lie with your tee shot. Neither of those thought it should be guaranteed. Trevino once proposed architects grind out just big enough to hit level spots at a succession of distances from the tee, starting at about 220, 240, 260, etc. I don't recall the exact figures, but he thought it might encourage more thought about not hitting driver on every tee.
Of course, many golfers believe its their architectural right to hit driver because chicks dig the long ball, I guess.
