Yes, like linear-gradient in that respect.

Are you considering ellipses at only 0 and 90 degrees? I don't like that limitation.

An ellipse can be specified with a center position, an angle for the primary axis, and an angle for shape of the ellipse (90deg is a circle, 0deg is a line).

Color stops would extend along the primary axis, measured from the center. Color-stop percentages would refer to the distance from the center point to the intersection of the primary axis with the side of the box, at the specified axis angle.

Default position would be centered. Default axis would be in the widest dimension. Default shape would have the 100% point on the minor axis touching a side. Simple vignettes would really be simple.
