It's very relevant in the context of whether Rust is a 'get things done' language. Implementing a linked list is not a characteristic task of 'getting things done' in Rust, just like implementing a hash table isn't a characteristic task of 'getting things done' in Python. And when you do need to do it, implementing a data structure isn't any harder in unsafe Rust than in C++.
