Why was the special case for None being "smaller" than all other

Because ordered comparisons (<, <=, >, >=) are much stricter in 3.0
than in 2.x.
In practice, ordered comparisons which don't have an obvious,
intuitive meaning
now raise a TypeError (such as comparing a number and a string).
That's fine. I'm just talking about the special case for None that
has existed in Python for years - and for a good reason.
How hard is it to implement your own "missing" object which has the
desired semantics? Why should something as fundamental as None have it?
