In the task-to-thread model, there are no threading mechanisms by which work could be offloaded onto another thread. As such, callback based asynchronous APIs which are not Swift async do not make sense. rdar://99047747

Have you considered using SE-0367? I think using that you can conditionally add the available attribute on the main declaration and avoid having to duplicate it.
So for example just above main declaration public struct CheckedContinuation, you can add:
#if SWIFT_STDLIB_TASK_TO_THREAD_MODEL_CONCURRENCY
@available(*, unavailable, message: "Unavailable in task-to-thread concurrency model")
#endifThere was a problem hiding this comment.
The implementation also changes.
