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.
