The 'stable_features' lint helps people progress from unstable to stable Rust by telling them when they no longer need a `feature` attribute because upstream Rust has declared it stable. This compares to the existing 'unstable_features', which is used to implement feature staging, and triggers on *any* use of `#[feature]`.
