Exactly: it doesn't at the moment, but eventually a future release could.

Of course, people using the latest stable `rustc` would likely never
see an issue. But there may be people e.g. building `bindgen` on their
own, and thus likely picking the latest version, while using an older
Rust toolchain from their distribution instead of, say, `rustup`.
