Rivers, streams, ponds, lakes courses built on islands are all Ok but not island greens, they have the ability to kill the game, slow up the game and make all those waiting to do the same. Big deal some can hit the Island green, but to what cost to the round and the round of others.
Island Greens are the product of a blank mind who can't find a real hazard to test the golfer, but he seems happy to kill the golfers game and day. Sorry, IMO they are the Devils work unlike the blind hole that test the golfers will and spirit.
You will never find Moses in the water of an island green, there nowhere to hide let alone go (unless down) and certainly not quickly.
