--- Comment #3 from Domenic Denicola <d@domenic.me> ---
While I agree that the override of [[HasInstance]] seems pretty pointless, I
don't understand why it would be future-hostile. JS versions of the classes
could just override their @@hasInstance, e.g.

```js
class WebIDLThingy {
  static [Symbol.hasInstance](x) {
    return performBrandCheck(x);
  }
}
```
