+* Tracking Issue: [#12235](https://github.com/rust-lang/cargo/issues/12235)
+
+A new `lints` tool table for `cargo` that can be used to configure lints emitted
+by `cargo` itself when `-Zcargo-lints` is used
+```toml
+[lints.cargo]
+implicit-features = "warn"
+```
+
+This will work with
+[RFC 2906 `workspace-deduplicate`](https://rust-lang.github.io/rfcs/2906-cargo-workspace-deduplicate.html):
+```toml
+[workspace.lints.cargo]
+implicit-features = "warn"
+
+[lints]
+workspace = true
+```
+
 # Stabilized and removed features
 
 ## Compile progress
