All that remains is its use to preserve the `arrayInstance.constructor = undefined` backward-compatibility possibilities. Proxies also observe it. I *really* wish we just had an @@new for this, such that new C(...args) is just shorthand for C[Symbol.new](...args) and the construct trap could be removed from proxies altogether. :-|
