Regarding the WP AUTHOR ENUMERATION BOT PROBE PROTECTION custom code, we were under the impression that RewriteRules must go inside the WordPress Rewrite loop, which is why the code was placed in Box 8 as opposed to Box 14.
This finding was a result of an email discussion we had back in 2017 (regarding the POST POST REQUEST ATTACK PROTECTION custom code). So, at the time, we made sure to move all of our RewriteRules (including the WP AUTHOR ENUMERATION BOT PROBE PROTECTION custom code) into Box 8 to ensure the code would function correctly.
Is this workaround no longer necessary?
