How to check if the component has a custom event listener if the event is provided in the emits property?

Demo

If I provide the emits option with "click", then the onClick gets removed from $attrs. Is there any way to check if the listener exists on the component?

<Widget @click="() => {}" />

// Widget.vue
emits: ["click"], // this makes $attrs.onClick undefined
computed: {
	hasClickListener() {
		return !!this.$attrs.onClick;
	}
},

I later found that there is a larger discussion about it. You can find the discussion and my current solution at vuejs/rfcs#397
