For me this is actually a reason to use React even if Vue might be more appropriate. I fear that the 'front-end ecosystem' is still a bit too much in flux to settle on a framework as relatively opinionated as Vue. What makes React both nice and complicated is that it's really pretty bare-bones (even with Redux), and as a consequence a lot of the stuff you learn with either be useful for JS programming in general, functional programming, and UI building in general. For example, I've been working on a little command-line tool in Elixir, and a lot of what I do in the view/render code is very much like React and what I learned by using React.
