So let me give you a specific example. If a site calls execCommand("LiveResize"), do we want this site to become completely unusable in WebKit, or do we want to ignore this? What about execCommand("ClearAuthenticationCache")?

If IE does the wrong thing that breaks sites in IE, it's their job to educate authors. But changing the spec would be useful is someone is up to it.
