First I would like to see if we can agree on the term superset. Like the question is typescript a superset of ES? As you pointed out there are many comment like solutions like jsdoc or like your pep 484 suggestion. But then a superset get narrowed down to // and /**/ which is fine but that means typescript doesn't come close as a super set and can never be used in jsbin directly for example.
So the big question is can we agree on a superset that stretches the boundaries so that typescript would fall under that category. If for example certain typescript syntax is too brought I can ask the typescript community if they can adjust their compiler in the future that is compatible with the Ecma superset specifications.
