Yes, definitely it may help if going with multiple clusters, however, there are also many scenarios that we don't want to maintain multiple clusters. For example, when we come to a SaaS platform, multi-tenant is pretty typical where different tenants may have different workloads, and workload management would be needed for different users, or even within the same tenant. So the "built-in" workload management (besides other features for multi-tenant) would be a big plus.
