That pattern falls apart when subclassing:
```js
class ImprovedArray extends Array {
/* implementation NOT overriding the `from` static method */
}
const {from} = ImprovedArray
from({0: 'abc', length: 1}) // Array instance instead of ImprovedArray instance
```
So, no, the `Array.from` precedent is a bad one.
