Nathan, I agree but have a hard time seeing the issue when it comes to changes that don't affect default behavior. Half of CSS3 doesn't make sense unless you read the spec in detail. If you don't get it, don't use it.
It also seems like a funny argument when it is clear that people don't grok the way it is now. Keeping default behavior the same, and adding an optional argument for those who do read the manual seems like a great step to me.
