Right, besides that, it also means that you cannot have a flexibly sized box with a background-color that extends out beyond the edge of the image in a single element, you mostly can't use background-position in its "normal" way without revealing some part of an unrelated image (unless you add a bunch of blank space between each segment of the image), and you cannot use background-size in a meaningful way.
