I dont think that GoS will have only 10 RL users, even if its private. But your points are kinda valid. EAC (other ACs as well) do know if a user has a manual mapped driver running or not (or mapped .dll), they just dont care if only a few people have that (like 3-4 people, not over 10) and if they notice that more and more people have the same driver running in private memory then EAC will ban them all in the next ban wave. There are many ways to dump a manually mapped driver and its even more easy if the cheat is internal. My point is, making it private doesnt change anything about the detection, EAC probably detects it but doesnt do anything and then we all think we are undetected. If u wanna be for real undetected then make the driver/mapper/cleaner,... perfect, in that way the anti-cheat doesnt see anything and GoS could still have over 200 users if they wanted to. Its a difficult topic to explain but as I said, ur points are valid especially "That does NOT mean private = undetectable.".
