It's perfectly possible to just use React on its own, without getting bogged down with all the other buzzword-of-the-week stuff around it.
React itself has been reasonably stable for a long time in Web terms. It is much more tightly scoped and smaller in its interface than most JS frameworks. There are a couple of major design trade-offs, which often seem to get overlooked in React advocacy, but if you have a bit of experience using it and understand the practical pros and cons then you can quickly decide whether the balance is favourable for some new project.
People who work in React spend way more time fixing toolchain stuff and trying to mix 10 artisanal-crafted "easy to reason about" libraries in order to accomplish tasks which are either solved or not even issues in other component frameworks.
Some people who work with React might. Plenty of others don't.
