Actually it's no biggie to have an optional style argument for basicConfig. People who don't use it don't have to specify it; the style argument would only apply if format was specified.

For some people, use of {} over % is more about personal taste than about the actual usage of str.format's flexibility; we may as well accommodate that preference, as it encourages in a small way the use of {}-formatting.
