Before this PR, $post was re-retrieved with get_post( $request['id'] ), presumably to account for anything changed as a result of update_additional_fields_for_object. After this PR, it is not re-retrieved anymore. Is this intentional?

This is how it works on the post controller. Just copying that format over.

wordpress-develop/src/wp-includes/rest-api/endpoints/class-wp-rest-posts-controller.php

Lines 884 to 905 in 7b9e33a

	$fields_update = $this->update_additional_fields_for_object( $post, $request );
	if ( is_wp_error( $fields_update ) ) {
	return $fields_update;
	}
	$request->set_param( 'context', 'edit' );
	// Filter is fired in WP_REST_Attachments_Controller subclass.
	if ( 'attachment' === $this->post_type ) {
	$response = $this->prepare_item_for_response( $post, $request );
	return rest_ensure_response( $response );
	}
	/** This action is documented in wp-includes/rest-api/endpoints/class-wp-rest-posts-controller.php */
	do_action( "rest_after_insert_{$this->post_type}", $post, $request, false );
	wp_after_insert_post( $post, true, $post_before );
	$response = $this->prepare_item_for_response( $post, $request );
	return rest_ensure_response( $response );
