Winter Witches and Fate patrons

[Alleran]

Winter Witches (the archetype) are limited to taking a patron from the following themes:

Ancestors, deception, enchantment, endurance, moon, occult, portents, stars, transformation, trickery, water, winter or wisdom.

Now that there's a new patron (Fate) that is used by Baba Yaga, would it be reasonable to include the Fate patron among these ones? It would seem to fit both with the general pattern of winter witch patrons (e.g. occult, portents, wisdom - they all fit to Fate as well) as well as with Baba Yaga in general (she is, after all, the one who created Irrisen, and witches seeking to follow in her footsteps are noted as often choosing the Fate patron).

Was it intended to be permissible for Winter Witches by design, or should it not be allowed? Because thematically at least, I can't see any reason to prohibit it.

I'm sure that as soon as it hits the PRD there will be clarification on the patron option. What book is this from?

I assume it's from the final part of the Adventure Path called Reign of Winter.

It's both in the final RoW book (Baba Yaga's article introduces it as her patron, and what witches who follow in her footsteps often take) and freely available on the Paizo blog:
