Rust 1.42
> Due to our stability policy, description will never be removed, and so this is as far as we can go.What Rust _should_ do is gradually increase the noisiness of warnings about using this. Eventually it'll disappear from the crate and end-user ecosystem  (possibly with a small effort to tidy up abandoned crates).Java's "never remove a deprecated API" was definitely one of their big mistakes. Even a 10-year deprecation cycle is better than none.
