I would say that Vulcan itself was never that important to Trek, dramatically, except as a foil to the Spock character.* It was always a rather two-dimensional place.
As for "Vulcan 2", that would be a total reset button cop-out. Others have already hit on the analogy of the Jewish Diaspora, where Israel was destroyed by "Nero", only to be reformed millenniums in the future. The dramatic possibility here is to show the plight of the "wandering vulcan", the aesthetic race with no home.
(*Well, T'Pol in Enterprise for all us 2 nielsons who watched it. Otherwise Vulcan itself was rarely referenced on-screen.)
