Unchecked exceptions are more like a shutdown event, which can be intercepted at any point along the call stack, which is useful and not like a return type.
Debugging. It's one of the most useful tools for narrowing down where an error is coming from and by far the biggest negative of Rust's Result-type error handling in my experience (panics can of course give a callstack but because of the value-based error being most commonly used this often is far away from the actual error).
(it is in principle possible to construct such a stack, potentially with more context, with a Result type, but I don't know of any way to do so that doesn't sacrifice a lot of performance because you're doing all the book-keeping even on caught errors where you don't use that information)
