Box is a bad example; it always has a value and can’t be unwrapped. It’s Result and Option that are the primary wrappers.
Result is for Errors, and Option is for nullables. If you consider it that way, the “issues” with unwrap are identical to other languages when errors and nulls aren’t properly handled.
