Is it Possible to Pass a Document Reference to Validation and Access the Dereferenced Fields?

import sanityClient from 'part:@sanity/base/client';

const client = sanityClient.withConfig({ apiVersion: '2021-08-06' });

// ...

export default {
  name: 'validationTest',
  title: 'Validation Test',
  type: 'document',
  fields: [
    {
      name: 'id',
      title: 'ID',
      type: 'string',
      validation: Rule => Rule.custom(async (doc) => {
        const match = await client.fetch(`*[_id == $id][0] {_id, title}`, { id: doc })
        <http://console.info|console.info>(match)
        return !match ? true : `This document already exists. Title: ${match.title}`
      })
    }
  ]
}
