Enforce API surface and semantic compatibility with 1.9.x branch    2. Improve the module‘s maintainability by reducing the storage        paths to a single mechanism.    3. Use the same single mechanism to support "private" and "user" data.    4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)    5. Avoid exposing implementation details on user objects (eg. expando properties)    6.
