I think I know the answer, but for clarity, if you already have the Dual Faiths talent, can you learn Pantheonistic spells if you have both deities as your patron? RAW, it looks like you probably need the Old Ways talent, but given how you get the Old Ways talent, it would seem more fitting to be able to learn Pantheonistic spells restricted to just those two deities with Learn Spell and Dual Faiths but any Pantheonistic spell with The Old Ways and Learn Spell, regardless of patrons, as long as it's Pantheon of Man. The whole concept of the Keeper of Forgotten Lore seem like it would be a better fit worship of the Pantheon of Man as a whole, like the old days
