Honestly - not a clue. It was like that when I got here, so the reasons are
probably lost in the depths of time. :-)
Trying to reverse engineer the decision, the most likely reason is that
Django has allowed callable defaults; if you define a callable in your
Django model as a default, there's no way to pass this down to the database
(or, at least, not an easy way).
