  # To maintain backwards compatibility, we accept both gl_repository or
  # repository paths as project identifiers. Our plan is to migrate to
  # gl_repository only with the following plan:
  # 9.2: Handle both possible values. Keep Gitlab-Shell sending only repo paths
  # 9.3 (or patch release): Make GitLab Shell pass gl_repository if present
  # 9.4 (or patch release): Make GitLab Shell always pass gl_repository
  # 9.5 (or patch release): Handle only gl_repository as project identifier on this method
