I would like to suggest to replace the 7G security by 8G security.

RewriteCond %{REQUEST_URI} ^/wp-json/wp/v2/users [OR] here

Could it be better to handle in another place?
Also, any known conflicts beside AJAX requests while using the admin pages? (at least with "pretty URLs")

Example from WordPress Developer Resources: Require Authentication for All Requests
--it's also possible to check if the request URI is /wp-json/wp/v2/users, in this scenario I've tested also with add_action('init', 'my_callback') and it was possible to block/redirect without the htaccess

This can also be useful Why is the REST API not verifying the incoming Origin header? Does this expose my site to CSRF attacks?
