Issue with Destination reducer in MainActor default isolation

[ryanbooker]

Has anyone had any issues with @Reducer in MainActor default isolation scenarios? I'm trying to add a Destination reducer and see the following in a MainActor isolated package:

extension MyFeature {
  @Reducer
  package enum Destination {
    case alert(AlertState<MyFeature.Action.Alert>)
  }
}

Conformance of 'MyFeature.Destination.State' to protocol 'CaseReducerState' crosses into main actor-isolated code and can cause data races

I had to manually paste the enum State @Reducer macro expansion and @MainActor isolate the CaseReducerState conformance.
