FWIW, I don’t see why the dogma was necessary either. I believe it 100%, but it doesn’t seem to fit with the other things that are necessary to the Faith. It is a fact, like, my date of birth, but I don’t understand why a fact must be a dogma.
I emphasize, however, that I do think it is a fact, and it is a truth worth defending regardless of dogmatic status. There was a time when many EOs felt the same way, too.

And the timing was driven by the advance of modernism among the people and even its influence within the Church’s clergy, monastics and hierarchy.
While I pretty much agree with Ghosty, I have to say (NB to the folks who are going to slam me for saying this, don’t bother: I will not engage in an argument) that the “timing” was likely driven more by the rise of Garibaldi and the impending peril of the Papal States than by anything else.
