Styling, layout and Dom composition are so tightly coupled that being a CSS only developer would be impossible. Particularly in the react world where everything is JavaScript, good luck trying to write a component and pass it on to someone else styling it. I agree that the scope of a front end developer is becoming very expansive, having to worry about accessibility concerns along with styling, performance, architecture is hard, but good teams usually cover all these things well enough combined.
