WAB, you are aware, are you not, that the date of the official dogmatic promulgation of a dogma does not have anything to do with the longevity of the belief?

Brethren of the Lord, neither the Gospel accounts nor the early Christians attest to the notion that Mary bore other children besides Jesus. The faithful knew, through the witness of Scripture and Tradition, that Jesus was Mary’s only child and that she remained a lifelong virgin.
An important historical document which supports the teaching of Mary’s perpetual virginity is the
