Change a l public declarations to the `package` access level, accept for: - The `LanguageServerProtocol` module - The `BuildServerProtocol` module - `InProcessClient.InProcessSourceKitLSPClient` - `LanguageServerProtocolJSONRPC` (I would like to create a more ergonomic API for this like `InProcessSourceKitLSPClient` in the future, but for now, we’ll leave it public) Unfortunately, our pattern of marking functions as `@_spi(Testing) public` no longer works with the `package` access level because declarations at the `package` access level cannot be marked as SPI. I have decided to just mark these functions as `package`. Alternatives would be: - Add an underscore to these functions, like we did for functions exposed for testing before the introduction of `SPI` - Use `@testable` import in the test targets and mark the methods as `internal` Resolves #1315 rdar://128295618
