What problem does this feature solve?

export default {
  setup() {
    const data = reactive({
      count: 0,
    });
    return { ...toRefs(data) }
  }
};

data is a proxy can we intercept spread operation, auto use toRef for all property, avoid manually toRefs? i don't know whether it is feasible thanks

What does the proposed API look like?

export default {
  setup() {
    const data = reactive({
      count: 0,
    });
    return { ...data }
  }
};

No that's not possible. WE would have to parse the JS AST for this, which is not something that would fit into the browser build.
