The key issue was not religious freedom itself: almost all parties in the various arguments supported some kind of religious tolerance. The dispute was over the traditional understanding of the relationship of the Catholic Church to secular states and how it supported relations with "confessional" states such as Spain and Italy. The declaration presented a view that fully supported the model of the church in the United States and the United Kingdom, while allowing for confessional states, and stated that it was based on development of doctrine from recent popes. Doctrinal development went from being somewhat suspect to a bedrock theological concept with Vatican II.
