You mention redux in your original comment and I wouldn't call redux store an imperative object. You have pure functions (reducers) updating a state, which is just a simple object without methods. The benefits I see in using this one application state is that I can easily debug the state of the application, I can easily serialize the whole state and include it in a crash report and the devtools for redux are very helpful. Although YMMV
