Good point, I forgot to mention that one of the main "problems" with diffusion curves as defined in the original paper(s) is that they completely do not fit in the normal "stack of objects with fill/stroke" idea. Basically they solve this by explicitly specifying the color on either side of each boundary, but this is not ideal (compared to simply superposing an object over a background for example) and some adhoc solutions are presented (in subsequent papers).
In contrast I (and others) would like to integrate diffusion curves into the normal "stack of objects" concept used in SVG, as this has some definite advantages when it comes to designing an image. Unfortunately this makes it a lot less obvious (to say the least) how "soft boundaries" can be supported. I have some ideas on this, but one of the outcomes could be that it is simply not that big a deal to combine the two, it might actually be more useful to simply have the ability to do a spatially varying blur *as well*.
I may be missing the point, but should it come down full control in one specific instance vs the ability to reuse a paint, I would choose full control to be able to get the most out of this technique. Seeing how a complex shading/paint/fill will be very dependent on the object, anyway.
