We need to know when we start loading the document which situation we're in. With your syntax, we can't know until the document is loaded. We use the presence of element() to signal that we're in the external resource situation.

Btw. you will run into the same problem with the 'fill' and 'stroke' properties. Both will take a paint server reference and a <image> value in SVG 2. (Resolved during the last SVG F2F.) This is why it makes more sense to be consistent IMO.
