What Should Be Added or Changed?

I'm playing FTB Evolution which has a custom world gen, afaik, which allows a player to go below -64 into so called infinity caves. Voidward triggers here, which means I can't go down there.

Why Should This Be Done?

Either give an option to toggle it, only activate it when void damage is taken, use the void starting height per dimension for the detection, or teleport the user to build height
