Keeping it out-of-line is unnecessary and has been since 5.0. In Qt 4.x, it was necessary to compare to the shared_null, which for QByteArray was a static variable. The one for QString has always been inline because the shared null was a static member of QString (in Qt 3, QString::null was a QString variable).
