This is used surprisingly often. For example, it is used by a core YouTube library called Structured Page Fragments. It allows you to manually dispatch an event with arbitrary data attached to it. The only thing missing from this implementation is the constructor. This is because WrapperGenerator is currently missing dictionary capabilities.
