Finally landed the first of many #SwiftLang standard library updates to replace "rethrows" with generic typed throws: https://github.com/apple/swift/pull/69771. The feature has been a fantastic exercise in generalizing in place: it maintains the same behavior for existing Swift code, maintains the stable ABI of the standard library, and yet any Swift code that adopts typed throws will see typed errors propagate through the standard library in the natural way.
