Parts 2 and 3, being the memoryview API and support for the new protocol in the builtin types are the parts that are currently restricted to simple linear memory views. That's largely because parts 2 and 3 are somewhat use case challenged: the key motivation behind PEP 3118 was so that libraries like NumPy, PIL and the like would have a common standard for data interchange.

If I understand correctly, one of the motivations behind memoryview() is to replace buffer() as a way to get cheap slicing without memory copies (it's used e.g. in the C IO library). I don't know whether the third-party types mentioned above could also benefit from that.
