There are lots of unstable things in Rust that have been unstable for many years, and the intentional segregating of unstable means that it's a nonstarter for most use cases, like libraries. It's unstable because there's significant enough issues that nobody wants to mark it as stable, no matter what those issues are.
As long as it's unstable it's totally fair to say Rust's stdlib does not expose them. You might as well say it's fixed because someone posted a patch on a mailing list somewhere.
