Should Arcane Fists give you Unarmed training progression the way Martial Artist Dedication does? This is the part I'm talking about:
"Whenever you gain a class feature that grants you expert or greater proficiency in certain weapons, you also gain that proficiency rank in all unarmed attacks."

No. The bonus skill is those extra skill points.

"Permanent Bonuses

Ability bonuses with a duration greater than 1 day actually increase the relevant ability score after 24 hours. Modify all skills and statistics related to that ability. This might cause you to gain skill points, hit points, and other bonuses. These bonuses should be noted separately in case they are removed."

So if I'm reading correctly, you get the retroactive skills from the Headband in the form of it's chosen skill, but when you level up, you get the extra ranks accordingly? Or nah?
