Of course people would like to see its' occasional use..Not everyone wants it kept in a museum. The Holy Father himself has said he wants us to view the Catholic Faith through a Lens of Continuity or Hermeneutic. That would indicate seeing a Tiara once in a while, maybe during the Blessings from the Balcony, as we have been seeing a Tiara on the heads of our Holy Fathers for over a 1000 years. Looking through the lens and seeing no evidence of it (the Tiara) is not continuity but rupture. Exactly what the Holy Father disparages.
