Sounds more like a discussion about restoring resistance to scoring to older courses - which is a different discussion from shot values.
To me, "shot values" connotes things like controlling trajectory - high or low; shaping a shot - draw or fade; controlling the release of the ball on the green; or aiming to particular areas of the green other than the pin. "Using every club in the bag" is a phrase which is over-used, and improperly used to denote variety of "shot values" on a course. If you had one course which required different length approaches from a 4-iron through a 9-iron, but which all were played with the same full swing and basic shot shape (say a high fade), and another which called for just 7 iron approaches, but one which was a knock-down, another a high fade, another a low draw, one which ran up 20 yards to a green sloped front to back, and another which had to stop quickly to a pin cut against a trap, it's an easy argument that the later course has the greater variety - though it uses less clubs than the former.
This discussion has much more of the Fazio "Golf Channel" interview - "they're hitting 9 irons instead of 7 irons, and something has to be done to stop them," than of analyzing the different shots traditional designs required.
As a final note - if you're really concerned about pace of play, do you really want to add 3 feet to the depth of each greenside bunker? (I guarantee that will add more than 30 minutes to each round).
