[Dask-on-Ray] How to set task priorities?

dask.distributed allows setting priorities for tasks (in case we have more work than workers, the scheduler knows which ones to execute first), it’s done via passing priority param to client.submit/compute/persist methods explained here. Is it possible to do this with dask_on_ray scheduler?

Task priority is currently not supported by Ray.

are task priorities still not supported?
How would one implement them with existing ray features? maybe with placement_group ?
