title: Will using NSRequiresCertificateTransparency have unintended behaviour?
body: <p>I am implementing certificate transparency using ATS settings for my custom domains. The official documentation <a href="https://developer.apple.com/documentation/bundleresources/information_property_list/nsrequirescertificatetransparency" rel="nofollow noreferrer">here</a>, gives a warning like this,</p>
  <blockquote>
  <p>&quot;Don’t use this key. The current system enforces this behavior, and
  new certificates can’t meet the requirement on older systems.&quot;</p>
  </blockquote>
  <p>I couldn't find any other documentation or release notes that explains this warning. My app supports 12.0 and above and I am not sure if adding this key will break my application in Prod.</p>
  <p>Is there any release note or doc that explains this warning so I can implement CT safely in my applications.</p>
