I think that we should ship this. It's a high profile and in-demand new feature <https://2022.stateofcss.com/en-US/usage/#missing_features_freeform>, so I have a few questions and comments first.
Taking a look at the open spec issues ( https://github.com/w3c/csswg-drafts/labels/css-nesting-1) some are explicitly ideas for future changes, but are there any where shipping amounts to a decision that isn't easily changed? I'm thinking especially of the CSSOM issues. In https://wpt.fyi/results/css/css-nesting there's a single subtest failure, related to how a rule serializes. Is that implemented per spec, or is it tied up with the open CSSOM issues? Regarding the threat of a formal objection, there doesn't appear to be any solution that would fully satisfy everyone, but I trust your judgment that this is the best option. Additionally, we should not pre-commit Blink to shipping parser changes, and accept the possibility that what we ship now is the final shape of the feature.
