I think the problem many developers see is the expectation that a "react developer" needs to know most of these things to call themselves such. It's a very similar issue to what many have with the term "full stack developer". It's a big leap between "I can get the job done if you want me to write some react code" and "I can write you an enterprise app in react", but both of those can be inferred as react development.
