Yes true, and to be clear, I think React is fine on it's own. It's just that from my view it's not fundamentally so superior as to warrant rewriting a decently structured app written in one of the other JS frameworks from the past few years. Especially if folks then go and have to reinvent/relearn, well, everything.

A lot of "React" excitement folks shared with me had more to do with using Webpack and ES6, which you can use with other frameworks.
