Well, the idea is to break the prototypal chain only to make data properties, defined on the "class", unique. Well, to say it better: i think the idea of MooTools minds about that, is the one i said.
That means that you cannot change the a data property on the prototype of a constructor function from an instance of that function itself!

About Implements, i think you right when you say it is not the same that in Java and Implements can be a confusing name... nothing to say about it. But i think aswell it can be an interesting tool to have and Js doesn't provide this kind of tools natively.

In the end, i think your considerations make sense but from my side, i don't think it is a so wrong to use a tool like Class inside a project.

All in my modest opinion,
Luca
