<wonder>Why would that mean to reject http://codereview.qt-project.org/16019 ?</wonder>

It just adds files that could be used for building Qt Creator with qbs, but it doesn't disrupt anybody's workflow as long as they use qmake. Which still is the only supported and required build system for Qt Creator. Any change that does not build with qmake will be rejected.
