Hi,
i always read such posts as if implementing redux is that big of an overhead like adding Ember or Backbone or any framework to your app. Redux simplifies managing your store, so even it's a small app, why not add redux to it? It makes sense all over the place. Redux is just plain functions, so no overhead, it's more a way to structure your app than any framework.
So: If you like redux and understand it, use it.
