[Amendment accepted] SE-0470: Global actor-isolated conformances

Hi all,

The review of an amendment to SE-0470 concluded on July 15, 2025. The language steering group has decided to accept the amendment as written.

Feedback was scant but positive for both proposed inference changes. It is understood that examining the requirements of a protocol to infer the isolation of a conformance means that the inferred isolation could change when a protocol gains new defaulted requirements—we lack a clean heuristic that would provide a workable alternative.

Thank you, as always, to all participants in this review process for helping to make Swift a better language.
