It is not, and a feature request is probably going to go nowhere.
The reason configurability seems like a bad idea is that null sort
direction is wired into things like index contents. If a user
were to flip the default null sort direction locally to his session,
then suddenly most of the indexes in the system would become unusable
to him. No doubt there are things that could be done to ameliorate
that, but overall it's just not apparent that the cost/benefit ratio
is reasonable for such a change.
