Pending review of WebKit's code to verify that the change isn't too
crazy to make, yes.

An SVG Stack doesn't work in 'fill' at all anyway.  The only property
with an ambiguity so far is the new 'mask'.  Soonish I hope to have
the ambiguity spread to all CSS properties that take an image, but
they'll default to images as they currently do, so it'll be fine
(you'll have to use element() to refer to an external resource).

Not really; at least, Stacks are an easier way to reference sprites.
Names are always simpler than coordinates, if you can get them.
