Would you still say it's a small API surface? State, memos, callbacks (which are just memo functions), effects, effect events, reducers, context, external stores, special handling for any tags that go in the `<head>`, form actions, form status, action state, activities, refs, imperative handles, transitions, optimistic updates, deferred updates, suspense, server components, compiler, SSR?

Or maybe it's a small enough API but a lot of concepts. Or maybe I'm just grumpy that the days of "it's just a view layer" feel long ago.
