There are entire classes of structures that no, aren't hard to do properly, but the borrow checker makes artificially hard due to design limitations that are known to be sub-optimal.

No, two-directional linked lists and partially editable data structures aren't inherently hard. It's a Rust limitation that a piece of code can't take enough ownership of them to edit they safely.
