I honestly do not think so, i agree with them introducing the new concurrent mode and hooks it does make it feel like a framework, but they are introduced to just expose the power of what react can do.
On broader terms we can choose our own libraries for various solutions to build apps along with react like, state management system (Redux, Kea, MobX), routing (traditional routers, react-routers, connected-react-router) , bundling (webpack, gulp), compilers (well not so much babel's the best).
Every 'library' is combined with React 'library' to build apps the way we want to build. :)
