Okay, I see. Printing `dict(options)` does output the keys:  
` 'instance_type', 'worker_resource_allocation', 'image', 'environment', 'idle_timeout_minutes'`  
But not the worker-options that I normally set.

I moved the discussion to [here](https://discourse.pangeo.io/t/no-longer-able-to-set-dask-gateway-gateway-cluster-options-manually-from-user-end/3851).
