They’ve already been looking into this internally.

Improve parallel scheduling and configuration:
In the current version of DOTS, all systems run on the main thread and rely on those systems to schedule jobs to enable parallelism. We’re investigating out-of-the-box parallelism of DOTS by enabling systems to run in parallel, whether or not they schedule jobs internally. We’re also investigating removing unnecessary dependencies between jobs coming from ECS systems which previously required manual intervention. Additionally, the job system is missing intuitive configuration controls needed for adjusting how jobs are run to best enable performance for individual game needs. We’re working on expanding the priority and control of how jobs run to prevent common issues users see, such as unintentionally waiting on long-running jobs on the main thread.
