The root failure with new SDK headers is sadly common. Everything else is fine, so I'm in favour of merging as is.

We were informed of root failure in issue #165757. It's a bit tricky that Xcode.app upgrade may break runtime behavior. Anyway, CI failure isn't related to numpy so should be good to merge.
