I expect that classes will eventually be extracted to a separate package and a codemod will be made available to update code to use that package, similar to what was done with React.createClass. The react team is very interested in making it easier to build UIs with React and they feel that hooks is the way to do this. So putting hooks in a separate package wouldn't have pushed their goals forward very well. I'm happy with the way it's been done so far. It's a change, and that comes with a learning curve, but it's one that I'm glad to have for the benefits that hooks provide.
That's an interesting insight, Kent. Thank you!
