I think bunker crews may become a thing of the past. This is a LOT of labor without much affect on playability, unless you're actually in the hazard.
But it could really help golf. The gauche excesses could disappear, CCFADs could end up being less expensive, and possibly open the game up to more people, especially if the price point decreases.
Places like Hickory Valley here in SE PA could be a model - inexpensive, decent architecture, walkable, and fun. If I recall correctly, a Saturday PM round at Hickory Valley costs less per hour than a movie.
