"Implicit acceptance" {or express acceptance, for that matter}is not a magisterial teaching, let alone a DE FIDE pronouncement. Nor is any reference to St. Vincent of Lerins. Likewise, the CJC is canonical, i.e disciplinary, and does  not carry the theological note of "dogmatic". Again, I implore you to read the final paragraph of DF and then try to put the square peg of "development of doctrine {dogma}" through that circle.
