That sounds reasonable.

This means that if the author wants the BODY element's background to
stay within the BODY element's borders, he has to explicitly set the
background color of the HTML element.

And if the user wants the HTML element a special colour with a border
on the BODY element, he can just set it, and it will not get
overridden by an author's 'background' rule on BODY.
