This always was a weak reason.

It is a matter of taste. For me s.expandtabs(3) looks more readable than s.expandtabs(tabsize=3).

I don't see an urgent need for this feature and don't like a complication. Let's defer this change until the passing of the keyword arguments will not be significantly optimized. I'm -0 for committing right now.
