The GM Camera is automatically registered as an Observer and spawns in groups marked with SCR_EAIGroupLifecyclePolicy.ProximityDriven
It may be useful sometimes to switch this off somewhere in a config, or even in the GM UI itself
One use-case is when testing our own group-spawning/virtualization systems. Or on a busy server with a PvE game mode (such as Overthrow) that spawns a lot of AI we might not want the GM camera blowing out the AI budget
