We have long standing consensus on the current ES6 class design and that includes a `super()` constructor call that can be arbitrarily placed within the constructor body. We had the discussion about an other forms forms of super constructor invocation, including special header forms, before reaching that consensus.
The motivating issue for the current discussion is that @@create can expose uninitialized instances, not whether we should move super constructor invocation into special declaration header form. Unless it directly relates to the solution of the @@create discussion I don't think we should be dropping our consensus on other aspects of the design.
