What is the official stand of Catholic Church on Luminous Mysteries of Rosary?

In the 16th century, Pope Pius V established a 15-Mysteries Rosary comprising of Joyful, Sorrowful and Glorious Mysteries. In the year 2002, Pope John Paul II added five Luminous Mysteries depicting key points of the Public Life of Jesus. There are different schools of thought as to whether the Luminous Mysteries form integral part of the devotion of Rosary, or not. The points of objection include a deviation from the matching of numbers of the Rosary beads used for three sets of Mysteries in 15 decades, that is 150 with the number of Psalms, vis-a-vis the number of beads now required to be used, that is 200, in case the complete Rosary is recited in one go. My question therefore is: **What is the official stand of Catholic Church on the inclusion of Luminous Mysteries as integral part of the devotion of Rosary?**
