Re: [parameters] Outline for recasting SVG Parameters on top of CSS Variables

Given that this allows an image to be completely changed I suspect we
wouldn't be willing to implement this feature to modify SVG-as-an-image
i.e. via the image tag or backgound images. Using it via the object or
iframe tags would be OK though.

If it gives you the ability to do something that a gif or png doesn't allow
then it breaks people's mental model of images. E.g. if you host a bulletin
board and you vet image uploads somehow as safe then you should not be able
to get around that by removing some part of the image to reveal a
completely different image.
