Why does CoroutineScope.cancel(cause: CancellationException? = null) return Unit instead of Nothing?
Is there a difference if we don’t have a noncancellation scope? When should we use cancel vs throw CancellationException?

Question comes down to job.cancel vs throw

You call cancel from outside of coroutine, you throw exception from inside of it.
