Supporter Pack Weapon Skins

I have a doubt about the weapon skins on the supporter packs. Let's take, for example, the spear skin in the King of Fariduns pack. The trailer says the skin can be used in spears and staffs in Path of Exile 1, but I can't apply it to staffa in Path of Exile 2.

I understand spears aren't in the Early Access, but does that mean that staffs in PoE2 will not be compatible with that skin, or do I just have to wait until the game is fully released?
