Journeyman Pro
The same could be said for lengths of rough, and any amount of growing items being different early in the morning to later in the afternoon.I just the club championship as an example. But you said that they would be raked only by the ground staff. That means periodically those out early get a distinct advantage.
For you average golfer a raked bunker is still a hazard, we aren't like the pro where we can float it to within a few inches. A bunker usually means we can get out (but not always) and we are less accurate than a chip shot.
Not raking bunkers would just mean it would be a lot harder for your average golfer for most of the time, while periodically a small group of golfers get a big benefit of raked bunkers.
Bunkers are a hazard, and we have to take the rough with the smooth.
