What problem does this feature solve?

A vue component should have a render() or setup(){return ()=>{}}, but definComponent or some other API can pass an empty object. Obviously an empty object as a component doesn't make sense. If we only had setup, we would have to distinguish between a hook and a component

What does the proposed API look like?

function isComponent(value: any): value is Component {
  if (value !== null && typeof value === 'object') {
    return (!!value.__v_component || !!value.__v_functionalComponent);
  }
  return false;
}

defineHook(()=>{}) or defineHook({setup()=>{}}) defineComponent(()=>{}) or defineHook({setup()=>{}})

Isn't this a feature request. I put all my suggestions in there. I want you to take a look at it and not just think I'm asking a question
