	 * Fast path: if the processor is already enqueued and the stored list is clean, there is nothing to write.
	 * This avoids taking the lock and re-reading the option on the hot path, which matters because
	 * DataSynchronizer::handle_continuous_background_sync() calls this on the 'shutdown' hook of every request
	 * when HPOS background sync runs in continuous mode. The check uses the (possibly request-cached) value;
	 * the authoritative re-read happens inside the critical section below only when an update is actually needed.
