Yes, the better player plays the air game today, but I play with guys whose handicaps go all the way up to 26 on a regular basis. Some of them are having to bounce the ball onto most of the greens on our course because they can't reach them in the air or if they can, they can't stop it quick enough. Therefore, for them, the ground game isn't just an option, it is the only way to get on the green in regulation (or 1 over regulation in some cases). Keeping the approaches interesting makes the game more interesting for them.
The same can be said of most women players. Even for many of the better players. When we setup a hole with a front hole location on the Futures Tour, many players did have to bounce it on to get it close. The better ones realized that, the others didn't.
As I go out to do USGA ratings at a lot of courses, especially those built in the dark ages of the 50s and 60s, I see the standard two bunkers pinching the approach down to 5 yards wide and forcing the air game to be the only way to play. This plays havoc on the weaker golfer and frequently means higher slope ratings as their extra landing area gets so narrow.
