That it’s possible to refactor rule conditions in GitLab CI/CD using the custom !reference tag

E.g. potential useful to merge common and specialized rules:

.common_rules: 
  if_on_main: '$CI_COMMIT_BRANCH == "main"' # Only run on "main"

deploy_to_prod:
  script:
    - echo "Deploying to PROD!"
  rules:
    - if: !reference [.common_rules, if_on_main]
      when: manual

Also works with rules defined in external YAML files included using the include directive.
