To watch out probably for Webkit "image-src" support is missing. We only support "-webkit-image-src"

Looks like the spec for this is https://drafts.csswg.org/css-images-4/#image-set-notation.
Should the prefixed variant be defined to behave exactly the same, or are there differences? @schenney-chromium do you know?

We would have a long road to remove the prefixed version because it is used in many Chrome and ChromeOS UI pages. Any change short of removing would also be challenging.
Fortunately, based on my understand of the parsing code and the spec, the -webkit-image-set spec is a syntactically valid subset of the image-set spec and the spec gives us a lot of scope in how to decide which image to use. So I don't see a need to adjust any spec based on back-compat and the implementation of image-set will be somewhat easier.

I think w3c/csswg-drafts#6285 is the most trivial way to go forward with this in terms of complexity of both specifications and implementations.

This can be closed, as w3c/csswg-drafts#6285 defined this in the CSS Images spec.
