Wasn't suggesting prior support, that's why I liked the Browser Compatibility table. Just trying to understand when is returning [0, 0] useful if we assume the method is always available. I may not know the entire context, but the jQuery ticket also says:

> ... and then proceed to the calculation below, which will give us an offset that may be incorrect, but it's closer than 0, 0, because it takes into account the scrollLeft and scrollTop.
