title: Twig embed vs include, any reason to use include
body: <p>Why not just always use embed? </p>
  
  <p>According to the docs the embed tag combines the behavior of the include and extend tags. </p>
  
  <p>I understand that in a lot of cases you don't need to do extend and only want to render the contents of another template, but it seems to me like you could just always use embed and serve that purpose. Are there any performance ramifications of embed to be aware of? Any functionality differences I'm missing?</p>
