As I said NS I personally think there should be a separate rating for working in a procedural environment in Class G.
We know what the ATCO needs to do to get separation and its relatively easy to either block there cunning plan if they are going to shaft you or facilitate things to move traffic.
But you need to know the procedural rules for separation and air law. You also need to know that you have absolutely zero protection apart from your ears and what ever toys you have fitted to your machine such as TCAS.
