I always thought the word "simpleness" didn't exist and this was even confirmed by some American friends of mine. However, I tried to look it up on some online dictionaries and I was surprised to find out that some of them report this word while others don't. What's the story behind "simpleness"?

OED has a number of similar definitions:
