Might be naive, but this has always been a concern of the view-model for me. Every GUI change results in a VM change via event/command. The VM becomes gospel for UI state which means reducers are much simpler, and my actual model doesn't care if it is indeed a button, expando, radio button or whatever else.

Isn't React pretty much a model-view-viewmodel architecture?

[Jenk]

Yes but it is easy to abuse/misuse IME, in that I think it requires one to maintain your own sense of discipline for the principle separation rather than the library/framework guide you into it. The threshold between UI and state management is comically easy to confuse.

Not dismissing it, mind, that inherent guidance is not something that is easy to achieve and I much prefer working with the likes of React than without.
