 /// For all types, `T: ?Sized`, and for all `t: &T` or `t: &mut T`, unsafe code may assume that
-/// the following properties hold. It is undefined behavior to produce a `t: &T` or `t: &mut T`
-/// which violates any of these properties.
+/// the following properties hold. Rust programmers must assume that, unless explicitly stated
+/// otherwise, any Rust code they did not author themselves may rely on these properties, and that
