Other comments:

As far as we can tell, the new features to Cascade since Level 3 do not affect security in any way; they just provide more sophisticated ways for authors to organize their style rules.

There is an [open issue](https://github.com/w3c/csswg-drafts/issues/4838) against the [@import chapter](https://www.w3.org/TR/css-cascade-5/#at-import) to get @import fetches properly defined against the [[FETCH]] model, so that cross-origin issues, etc., are well-defined. We are attempting to fix this, but the Fetch spec is still somewhat troublesome to author against, and there are few examples of correct usage (even the HTML spec is still broken in this respect). We anticipate this will be fixed in a future CR publication, before requesting advancement to REC, and welcome any help in getting it right.

Please let us know how long to wait for your review, and let us know us if you complete review without finding any issues.
