  description: Record the reversibility posture of the batch export write surface.
  update:
    x-reversibility: batch_exports_pause_create / batch_exports_unpause_create is a fully symmetric reversal;
      batch_exports_backfill_create is the compensating replay for a gap; batch_exports_destroy is permanent.
      No time window is published for any of them.
