The CA/B Forum did in fact ratify these rules, which is why they're in its "Baseline Requirements".
They (I would say deliberately) stalled the process to actually make those rules binding on the CAs and that is where Mozilla used their fiat powers to just require this anyway, knowing that all the other trust stores would come for the ride and actually nobody at CA/B offered a legitimate reason not to do this, they just (again I would say deliberately) allowed it to get procedurally bogged down so that nothing would happen for a period of time.
