Who cares?... interesting question...
I think the general golfing public, including cart ballers, joe 6 pack, and most who belong to private clubs WOULD care. I think they would be pretty pissed actually if they reduced the length their ball travels. You just made a hard game harder. Also I think you take away a lot of the excitement that hitting a big drive creates... remember most golfers NEVER break 100, they swing as hard as they can every time they tee it up. Some times the best memory they have of their entire round is that 1 drive where they finally squared the clubface and smoked one down the middle... when the ball rolls back, I think you are going to lose a lot of the top-flite playing, cart driving, wrong tee playing golfers. Remember most golfers introduction to the game comes at the driving range, where most are trying to drive the ball over the fence.
At the same time... The extreme distance the pros get is killing our classic courses. Shot values are lost, and some of the best courses are trying to change to keep up with them.
I think either the tour needs to roll the ball back so they can continue to play the classic courses, or they need to take their tournaments to courses that can handle the distance, because its not right to ruin classic architecture for the few days when the pros come to town
