Can anyone provide some realistic use cases?  I've read the whole thread and I can only recall at most one, viz. the default value is expensive to compute and may not be needed. 


This library is widely used, extremely powerful, and expressive. Basically, a built-in capability would have every win of Dask Delayed, but decrease the impedance mismatch (which isn't terrible as-is) and avoid the need for external tooling.
