The timing of the Rome's announcement of an Apostolic Constitution was driven by the General Synod's determination to allow women bishops in the Church of England without an accommodation for traditionalists that would diminish the power of women bishops. The purpose of the Apostolic Constitution is to give traditionalists leverage so that a cadre of the Church of England remains untainted for a future unification. Rome expects that in the equilibrium of this strategic game the Church of England will cave in to the traditionalists; it does not expect to more than a few C of E members to cross the Tiber. Power play, poaching, or pastoral response? It's power play, out of weakness perhaps, but power play.
