This thread was somehow left unresolved. For reference, the proposal got returned for revision back in May, with the notes below. > [@\[Returned for revision\] SE-0427: Noncopyable generics](https://forums.swift.org/t/returned-for-revision-se-0427-noncopyable-generics/72039): > > The [review](https://forums.swift.org/t/se-0427-noncopyable-generics/70525) of [SE-0427: Noncopyable generics](https://github.com/apple/swift-evolution/blob/main/proposals/0427-noncopyable-generics.md) has concluded and the feedback was positive overall - reviewers acknowledged that the problem solved by SE-0427 is extremely important for Swift's ownership story, and many noted that they are excited to use the feature.
