I think this would fall in the category of clipping to arbitrary objects. Personally, I'd love to see this added as it would make some interesting effects easier to implement, but it's certainly not trivial and could have a performance impact.
Right now clipping is restricted to rectangles, so the clipping color is applied through blending a single color with the clipped pixels. To do arbitrary clipping it would require rendering the clipping pixels to a buffer, then blending the clipping pixels with the clipped pixels. Another option is providing a clipping operation for each primitive to perform the clip/blend operation.
