I've been speaking to @vieiro who is tackling 11u - albeit these changes are even more complex than 17u but I'm happy to help where possible.

8u is a much harder one to fix, one thing I'd considered was bumping the CI to macos-12 (which is still in support) and has [xcode 13.x installed on it](https://github.com/actions/runner-images/blob/main/images/macos/macos-12-Readme.md#xcode). This would only be pushing the problem down the road for now but would at least get 8u green again. WDYT?
