Actually, if you suppose that most radial gradients are going to be used in backgrounds, then the current syntax is already over-complex, and should just be reduced down to the following, to be centered in the image box and filling it to the sides:
radial-gradient(<color-stop>[, <color-stop>]+)
The rest could be mostly handled by background properties, especially 'background-position' and 'background-size'.* Any other added complexity to the syntax would mainly benefit 'list-style-image'. I can't see that there would be a lot of demand for stretched radial gradients with a lot of controls in border images. So really the question is how much more control do we really need for bullet point radial gradients, which would also give a little more control in border-image radial gradients as a bonus? Or does anyone really think it is important to be able to tile radial gradients that are clipped in unusual ways to rectangular boxes, without using SVG to do it?
* I would also propose that 'background-size:cover' would work a little differently for radial-gradient images, so that the gradient goes from center to corners ('background-size:contain' would go from center to edges).
