 The tracking issue for this feature is: [#95228]
 
 [#95228]: https://github.com/rust-lang/rust/issues/95228
 -----
 
-The `strict_provenance` feature allows to enable the `fuzzy_provenance_casts` and `lossy_provenance_casts` lints.
+The `strict_provenance_lints` feature allows to enable the `fuzzy_provenance_casts` and `lossy_provenance_casts` lints.
 These lint on casts between integers and pointers, that are recommended against or invalid in the strict provenance model.
-The same feature gate is also used for the experimental strict provenance API in `std` (actually `core`).
 
 ## Example
 
 ```rust
