Prevent User Enumeration

By scanning WordPress url's it is possible to find valid user accounts for use with brute force attacks.. This can possible be prevented by using techniques like on this page: https://perishablepress.com/stop-user-enumeration-wordpress/ My question is: can WPMU Dev's please investigate this technique and if it's working, include it in the Defender Plugin? (there is a .htaccess solution). Thank you very much !!
