We should be able to update collections/fields with populated data. E.g.,:

{
  shop: {
    id: '63bb051e53c9a3b0f68c4a16',
    name: 'Amazon',
    createdAt: '2023-01-08T18:02:06.334Z',
    updatedAt: '2023-01-08T18:02:06.334Z'
  },
  last_checked: 'Thu Mar 16 2023 15:52:48 GMT+0100 (Central European Standard Time)'
}

instead of the flattened version:

{
  shop: '63bb051e53c9a3b0f68c4a16',
  last_checked: 'Thu Mar 16 2023 15:52:48 GMT+0100 (Central European Standard Time)'
}

Use-Case

Imagine you first get a collection from payload, then modify it, then you want to update it again with the modified values.

If you pulled the collection from payload with a higher depth than 0, you're screwed, because then you'd need to manually flatten all relationships/populated values.
This becomes VERY, VERY painful with multiple, recursive relationships/populated values, which is why I'd consider this essential.
