Doesn't look like there is. I think the idea is for this to be a nontrivial example of a full-stack Haskell+Nix(Ops) project. The Twitter part is meant to be more familiar that robust. It's fair to argue auth should be included in a nontrivial example though. I honestly don't think it would add that much clutter either. Although unlike the other components, I don't know if there's a simple off-the-shelf Haskell solution for auth.
