Has anyone made a basic list of corals that actually need feeding and those that get what they need from light?
As Ben mentioned, there are a few corals, that absolutely require feeding. These are Non-photosynthetic corals, that do not receive any benefit, from sunlight. Each head needs to receive food.
Most other corals will benefit, from feeding, but it's not required, as long as you're meeting their lighting needs. Even photosynthetic corals, that don't receive appropriate lighting, can be "helped" by additional feedings.
I'd caution those, who feed their corals, to carefully monitor their water quality. It's much easier to end up with nitrate and phosphate issues, when feeding our corals.
Very true that trying too hard to feed your corals can lead to a water disaster, but if you carefully feed each polyp and keep a good clean up crew, you shouldn't have too much of a problem. I wouldn't feed more than 3 times per week, unless you see every last bit consumed.
I don't hesitate to overfeed a little because I have lots of shrimp, large and mini brittle stars, and a huge population of giant bristleworms.
