Fair enough, @hube2!

We were able to bypass this issue by manually exposing the field:

function our_expose_attribution() {
	// Field name to register.
	$field = 'attribution';
	register_rest_field(
		'attachment',
		$field,
		array(
			'get_callback' => function ( $object ) use ( $field ) {
				// Get field as single value from post meta.
				return get_post_meta( $object['id'], $field, true );
			},
			'update_callback' => function ( $value, $object ) use ( $field ) {
				// Update the field/meta value.
				update_post_meta( $object->ID, $field, $value );
			},
			'schema' => array(
				'type' => 'string',
				'arg_options' => array(
					'sanitize_callback' => function ( $value ) {
						// Make the value safe for storage.
						return sanitize_text_field( $value );
					},
					'validate_callback' => function ( $value ) {
						// Validate
						return is_string( $value );
					},
				),
			),
		)
	);
}
add_action( 'rest_api_init', 'our_expose_attribution' );
