Pathfinder concoction skills cant use heralds or wind dancer now

With the change to concoction skills to require unarmed, you cannot use heralds or wind dancer now as those require a martial weapon. I feel this is an unintended consequence of that change?\

I understand GGG didn't want weapon stats being used for concoction skills but it would be nice if these skills could also be used unarmed, maybe use the concoction skills damage as the base dmg for heralds.
