title: github CODEOWNERS: Disable email notifications for default owners
body: <p>Is there a way to disable email notifications to the default owners configured in a github CODEOWNERS file?</p>
  
  <p>In <a href="https://help.github.com/en/articles/about-code-owners" rel="noreferrer">the code owners documentation</a>, I can only find the following:</p>
  
  <blockquote>
    <p>These owners will be the default owners for everything in
    the repo. Unless a later match takes precedence,
    @global-owner1 and @global-owner2 will be requested for
    review when someone opens a pull request.</p>
    
    <p>@global-owner1 @global-owner2</p>
  </blockquote>
  
  <p>While I do want to have the default code owners, I don't want an email notification being sent out to each code owner for each push, review remark, review approval, merge, etc. It's to much spam and makes it easy to overlook important notifications, e.g., when someone is explicitly added as a reviewer or mentioned in a comment.</p>
