Can we write tests that validates no user-code would be run? I think this can be simplified to

Suggested change
const set = new Set();
this.forEach((value) => primordials.SetPrototypeAdd(set, value));
return set;
return new Set(this);

(given the triviality of the implementation, I wonder if it actually makes sense to add a method for that)

Sure! I couldn't find anywhere SafeSet is already tested, so i'm not sure where to add them - any suggestions?

I guess this is a valid simplification since it has a safe [Symbol.iterator] on it, in which case you're right, it's probably not needed. I was assuming add-at-construction-time wasn't an option.
