In practice, this turns out to not work how we want because `std::unexpected` imposes more constraints on it's template parameter than we do (it can't be a forward declared type). It'd be nice if we could reuse types, but given it's a compilation error remove them in favor of always using our own types. PiperOrigin-RevId: 907144725
