It seems to be important to distinguish between the Ecma-262 editions.
Your notes seem to take into account only Ecma-262 Edition 3. Edition
5.1 (or maybe 5 already) introduced Object.seal()[1] which can be
applied to the prototype object. Ecma-262 Edition 6 might introduce
"maximally minimal" classes[2] and private name objects[3] which would
provide better support for classes in the classical sense.
