When it comes to thaumaturgy and Fate Core, I've been seeing a lot of different ways to do different things that fall within thaum's purview, but it's not like thaum in that there's one grand unified system to do everything.
Want to summon something? Check out Storm Summoners or Void Callers in the magic toolkit preview. Want to cast a small blessing or curse? Try the Subtle Art. That sort of thing, where you could take mechanics from several subsystems to simulate some of what thaumaturgy can do, but we don't yet have an exact translation.
