* Most developers are not writing data structures, so optimizing for that seems unnecessary.
* There is work and research going into verifying unsafe code
* I think historically we can see that most memory safety vulnerabilities are not going to be in some lower level data structure, which is well encapsulated and likely already built by someone else, but in the use of that data structure. In particular - sharing references and also invalidating data safely without leaving references to that data. Rust helps you here, and this seems like the far better target.
* Even if your rust code uses unsafe, you still have benefits - you know where to audit for unsafety, you know where to pay extra close attention, and you can still write a large portion of your code in safe rust.
