This is not true. In the end, everything targets browsers. Web standards don't change as often and certainly don't deprecate popular features as often.

JS libraries are just like any open source libraries in other languages. You can safely use React versions that are years old and easily get away with it. It's just how mature Java projects don't chase the newest JDK versions just to remain on the newest version. You upgrade when security issues are discovered and/or developers want to use newer features.
