> React can be 100% stateless, functional, and have the state live somewhere else. You just need to apply the same limitations as your model: components should be simple and not store data in themselves.

"just" is doing a lot of heavy lifting here. Where do you store "pure" GUI state (button state, is expandable expanded, …)? Do you really want to setup Redux for this? (And no, the DOM is not an option in non-trivial cases.)

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.

I'm not defending this model anywhere. I'm just stating that React can do what applfanboysbgon suggested: "As a game developer working in my own engine, UI is unbelievably straight-forward: [...]"
