Currently, pods' request resource requirements are considered for computing node resource utilization in the strategy "LowNodeUtilization", is it more rational to use actual node resource utilization as judgement?

It is common that resource limit of pod is larger than request, and after the scheduling of default scheduler (by resource request), It's probably that cluster is balanced. But the actual resources usage of pod could be much larger than request, which may lead some nodes under pressure.

So is it much more reasonable to combine with metrics server and use actual node resource utilization.
