Mayday,
Not 100% sure what you don't like, but I will explain the side bunker theory as I have heard it from pros who also think about design.
-Good players don't hit short very often, but they do hit approach shots wide (10% of total approach shot width is a good 2 out of 3 estimate)
-Average players hit it short, and wide (about 15% of approach shot width, favoring the right, of course.)
-Frontal bunkers only hinder average and below players, lateral bunkers snare good players, too. Thus, it is wiser to use lateral bunkers at the green.
Now, if you are arguing that those side bunkers should have a little angle to set up one side or the other as prime tee shot landing area, I would agree. If you say visually, a bunker parallel to centerline of play isn't as artistic as those with 10-30 deg. angles to the centerline of play, I would agree. If you are arguing "bunker left, bunker right" gets boring, I would agree.
