never has several of these interesting use-cases. Perhaps we should document them somewhere 🤔
For example, Schedule.never is build on top of IO. never, and can be used in a similar way as we do here with IO.never. Same goes for Stream.never etc.

It's also useful to wait for cancellation: onCancel({ never<Unit>() }) { println("Execute on cancel") }.
