But as Allen said, [[Invoke]] is not a performance hack. It's a
correctness hack.

It permits proxies to customize their behavior around `this`, and even
naive .invoke trap users would definitely want those customizations to
apply for implicit .toString() and .then().

Sorry, how can this be correctness when ECMA-262 and implementations have used [[Get]] + [[Call]] (after some IsCallable conditioning) forever?
