The proposal was [accepted with modifications](https://forums.swift.org/t/accepted-with-modifications-se-0428-resolve-distributedactor-protocols/71366) The decision was made to change the spelling of the attached macro in the proposal from @DistributedProtocol to `@Resolvable` (or `@Distributed.Resolvable` if disambiguation is needed).
