I don't think there's much doubt that it will add conversions between the two to Rust code, requiring more code to get stuff done. It won't improve either safety or performance to be using it in the library API boundaries. It may aid in writing correct code by catching programmer errors, but there has yet to be someone arguing that this is the case with compelling examples.
