Pattern: Prevent <script setup> variables used in <template> to be marked as unused

Issue: -

Description

Without this rule this code triggers warning:

<script setup>
  // imported components are also directly usable in template
  import Foo from './Foo.vue'
  import { ref } from 'vue'

  // write Composition API code just like in a normal setup()
  // but no need to manually return everything
  const count = ref(0)
  const inc = () => {
    count.value++
  }
</script>

<template>
  <Foo :count="count" @click="inc" />
</template>

After turning on, Foo is being marked as used and no-unused-vars rule doesn't report an issue.

When Not To Use It

If you are not using <script setup> or if you do not use the no-unused-vars rule then you can disable this rule.
