Ask HN: What are industry implications /applications of Structured Concurrency

Swift as of of the first languages embedded structured concurrency into their latest update. I think I do understand the implication as it guarantees a child task to be finished before the parent task. I understand it in a way that one can avoid race conditions altogether.

However, I'd like to know if this is a great deal and if so what it can mean for industry applications? What can now be done what could not be done before? What can be approved what could be fore?
