The current behavior is clearly documented in the Rust Reference[1]:
>The following language level features cannot be used in the safe subset of Rust:
> Dereferencing a raw pointer.
> Reading or writing a mutable or external static variable.
> Accessing a field of a union, other than to assign to it.
> Calling an unsafe function (including an intrinsic or foreign function).
> Implementing an unsafe trait.
It also calls out the behavior in noted in this specific post in "Behavior not considered unsafe"[2]:
> Exposing randomized base addresses through pointer leaks
