Of course, it's easy to add a new type for this, but a lot of Python 2 code relies on None behaving this way, esp. code that reads data from databases, since None is the Python mapping for SQL NULL.
At the same time a lot of Python 2 relies on the assumption that any two values are comparable. I suppose that I see a code that try to sort a heterogeneous list more often than a code which want to sort a list containing only numbers and Nones.
