In some other overrides in this PR, we implement this like `return new 
UnmodifiableNavigableSet<>(ns.reversed());`. Is there a semantical difference 
between that style compared to using `ReverseOrderListView.of(this, false);`? 
In other words, for consistency, can this override be implemented as:


return new UnmodifiableList<>(list.reversed());
