I'm reposting a separate mini-proposal: Remove Sendable conformance from unsafe pointer types (proposal PR).
I extracted this proposal from the larger proposal: Improving Sendable Inference.
I didn't see any concern about changing unsafe pointer types in the pitch thread for the larger proposal. And I don't think there is any dependency or close relationship between the other proposed changes:
- Sendable KeyPath literals
- Non-Sendable keyword
- Generic Sendable inference
- Compile time control over SEndable enforcement
An early discussion of the unsafe pointer change was positive.
