But most of those administrative links including edit comments are enabled or presented to you only if you are logged in. So why bother?
Even if the bots somehow manage to trace them, most wordpress webmasters stop the bots using robots.txt and the requirement to login is only an extra step to prevent those nasty not so obedient bots.
I even go further to restrict access to wp-admin folder to my ip address. So the bots or users would never be presented with a login page and a 403 is issued.
