My impression was that the discussion on that pooint was inconclusive. This
margin note has been in the ES6 draft for a couple of years:
"At Jan 29, 2012 TC39 serveral peopled suggest that this fall back was
unnecessary complexity and that it should this throw. However, that means that
an ECMAScript function whose __proto__ is set to null will throw if newed. I’m
not sure that is desirable. It’s a breaking change for the reality web."
I don't think we had consensus about whether we are willing to accept such a
breaking change. However, the eliminating [[Construct]] path would probably
push me over the edge into accepting that.
