How much consideration is given to soft affinity for consolidation?

Description

I have read document consolidation, but there is something I would like to ask about.

In the process of node consolidation, should the controller focus on minimizing costs or balance cost reduction with maximizing the satisfaction of preferredDuringSchedulingIgnoredDuringExecution constraints?

Consolidation is designed to group nodes to achieve the lowest possible cost. However, the level of consideration given to preferredDuringSchedulingIgnoredDuringExecution is less clear. While requiredDuringSchedulingIgnoredDuringExecution mandates strict adherence during consolidation, preferredDuringSchedulingIgnoredDuringExecution only represents a preference and is not strictly enforced.
