 In http://localhost/wp-admin/network/site-new.php, if we input everything
 except Site Title, which shows it is required, the process of adding is
 still going well.

 It is because in `wp_prepare_site_data()` function, the
 $allowed_data_fields did not contain field "title".  You will see that in
 wp_normalize_site_data(), it contains "title", but later in
 wp_validate_site_data action, $data did not contain "title", and there is
 actually no checking on this field.

 Please add this title validation back to the process.

 Thank you
