Agreed, mine too has all these "sub settings" of beach, snow....etc....etc....never really used them. I once tried out a couple vs manual set up. I noticed that the pixel size drops depending on what setting you use. For instance, "portrait" will only go up to 6meg, yet I can shoot the same image in full 12meg if I take the time to set up the camera properly in manual. Similarly, "Fireworks" racks the ISO up to 800, which isn't very pleasing to the eye on my camera, yet when I took some in manual, I got much nicer ones at ISO200 and a longer shutter speed.
These different Auto settings are fine for compact point and shoots, as without wanting to come across elitest, the majority of folks using them are wanting to basically do just that.
With a Dslr/Bridge, you assume that the photographer is more savvy and wants to take shots that are a bit more detailed and planned out, therefore would be making the most of manual control to achieve that, making the Auto sub settings redundant.
I feel instead of migrating point and shoot attributes over to higher end cameras, the manufacturers could make better use of the software and extend the manual experience.
Just my humble opinion
