Visibly, there's a need for a summary:

pros: - simple to read and understand
      - feature needed by users

cons: - new constraints needed on rule insertion
      - new constraints needed on rule deletion
      - @else standalone after deletion of @media is meaningless
      - complexifies automated media queries management
      - can't always express the @else case by a MQ
      - issues with copy/paste in wysiwyg environments
