I think it's less about responsibilities during the fight, but rather they don't want people arguing about who gets to trigger the parries that were added from the boss's auto attacks. So they are dividing it into "parry tanks" and "non-parry tanks" and having it be specific to certain jobs makes it simpler in party finder to ensure you only have one tank that can even benefit from being auto attacked.

Except damage from tanks is probably one of the last things to actually optimize so they are also saying that they will somehow get the balance of main tanking having better personal mitigation and off tanks having more party mitigation work. A lot of us are very skeptical of this because party mit is way more important than the tank's ability to survive. If a tank dies it's usually a minor inconvenience; if the party dies then it's a wipe.
