Not that the optimization would even matter... [especially] for the purposes of this one-off module.exports:

```javascript
d8> var start = Date.now(); var o = { foo: 1, bar: 2, baz: 3}; o.foo = void 0; o.bar = void 0; o.baz = void 0; new Date() - start;
0
d8> var start = Date.now(); var o = { foo: 1, bar: 2, baz: 3}; delete o.foo; delete o.bar; delete o.baz; new Date() - start;
0
```
