Can we settle on this model? If their are still doubts and requests for readonly<Foo> instead, we should resolve them before we introduce APIs that need to be deprecated later. Does the stringifier for Foo look different to FooReadOnly? I would expect so, otherwise we would need to introduce an indicator for web developers if the current object is readonly.
