Is it okay to return non-reactive values from a composable?

E.g., like so:

// useNavLink.js

import { toValue } from 'vue'
import { useRouter } from 'vue-router'

export default function useNavLink(link) {
  const router = useRouter()

  const handleLinkClick = (ev) => {
    ev.preventDefault()

    router.push(toValue(link))
  }

  return { handleLinkClick }
}

// NavLink.vue

<template>
  <a :href="link" @click="handleLinkClick">{{ label }}</a>
</template>

<script setup>
import useNavLink from '@/composables/useNavLink'

const { link, label } = defineProps(['link', 'label'])

const { handleLinkClick } = useNavLink(() => link)
</script>

The docs say the following,

The recommended convention is for composables to always return a plain, non-reactive object containing multiple refs.

but they don’t explicitly say that one shouldn’t return non-reactive values.
