I think there should be an ignore option added in the hardener area. Some things you cannot do on a shared hosting environment and I do not like seeing in my WPMU DEV Hub that I have problems that I cannot fix. Is this something that can be added?
An example of this would be to disable directory browsing/prevent information disclosure. I do not have access to an NGINX.conf file to make these changes and SiteGround will not do it, nor will any other host.
