When it comes to the Now in Android sample app , why is it good/ok that NiaAppState is not a ViewModel? We have

MainActivity

NiaApp

NiaAppState

UserNewsResourceRepository

and in all of this there's no ViewModel involved. As soon as we move to using Compose, how do we decide when a ViewModel is and isn't necessary?

see the comment just above yours. Not everything needs to be in a viewmodel, depending on your needs it's perfectly fine to store this in a state holder, as in the case of this example in the Nia app
