Goal: As an OpenShift administrator, I require support for the existing capability (as of Kubernetes 1.20, OCP 4.7) to optionally not allocate a NodePort for Services of type LoadBalancer.

Problem:
This is useful for VIP-based implementations of Service Type=LoadBalancer where the node port is not needed, like MetalLB, otherwise unnecessarily exposed ports can fail regulatory/compliance requirements, and the number of Services of type LoadBalancer is limited by the number of available node ports.
