I think there is also a real-worldish performance concern in current engines with the `:is()` insertion approach. When you have `:is(a, b) c` you can't use the ancestor bloom filter to reject the selector quickly outside the `a` and `b` subtrees. The ancestor filter is often the optimization that enables decent performance with complex stylesheets. -- GitHub Notification of comment by anttijk Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/8310#issuecomment-1387219067 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
