// It's definitely not something expected for plugin developers,
	// and registering UpdateNodeTaint event is the only mitigation for now.
	// So, kube-scheduler registers UpdateNodeTaint event for plugins that has NodeAdded event, but don't have UpdateNodeTaint event.
	// It has a bad impact for the requeuing efficiency though, a lot better than some Pods being stuck in the
	// unschedulable pod pool.

- Improved the efficiency of NodeAdded QueueingHint by registering UpdateNodeTaint event for plugins that have NodeAdded event but don't have UpdateNodeTaint event. This ensures better requeuing efficiency and prevents Pods from being stuck in the unschedulable pod pool.
