## Review Conclusion

Thanks to everyone for the feedback. Given the arguments against the deprecation warning, the core team has decided to [accept](https://forums.swift.org/t/accepted-se-0268-refine-didset-semantic/31822) the _original_ proposal, of altering the fetch semantics without deprecating the implicit `oldValue`.

Thanks to everyone for the thoughtful discussion of the merits.

Ben
