You hear fairly similar statements about linked lists from the C++ crowd too, where they're trivial to implement, so it's unlikely it's just defensive excuses.

They are are arguably about as trivial to implement in Rust. It becomes tricky when you add constraints: usually you want to avoid unsafe code, but even then you can just implement them on top of a vector and bypass any lifetime/aliasing issues.
