  // Equality on arrays with list type of 'set' or 'map' ignores element order, i.e. [1, 2] == [2, 1].
  // Concatenation on arrays with x-kubernetes-list-type use the semantics of the list type:
  //   - 'set': `X + Y` performs a union where the array positions of all elements in `X` are preserved and
  //     non-intersecting elements in `Y` are appended, retaining their partial order.
