There certainly isn't one concrete scheduler that works for all workloads. It probably doesn't matter for server or supercomputer environments; as long as some scheduler works, it doesn't have to change. For other use cases, the scheduler should be flexible with throughput and fairness. Priority, resource usage, realtime, but more cohesive. Tuning the scheduler might be harder in such a design, but it should allow for users to not need to switch to a different base entirely. It'd be more of a scheduler framework that can be used to support various workloads dynamically.
