The operator

(side bit first I did read the rules and I hope I did the spoiler thing right. if not let me know and I'll fix it)

Sorry if the title is too vague. I wanted to try and not spoil anything for those that don't know. but I got to ask. I've looked into it. I've tried finding an answer, but I haven't. Are we supposed to stop using the operator at a certain point? I don't mean never use the operator/drifter again only frame. I mean everything after new war seems to be drifter focused. I didn't think about it at first when the back rooms only allowed drifter to walk around but then it hit me. when I tried to go to the temple in the portal to help urial frame guy it's said if I want to go in there, I have to switch to the drifter. not auto change me to the drifter like it does in other places, and then change me back automatically when I left there. no I have to manually set myself to play as the drifter every time I want to go in there. then I realized most quests and locations after new war are drifter focused.

So, my question in short is are we supposed to just dump kiddo us like old trash and use the drifter at some point?

Update I should probably make this clear. I'm specifically talking about a Lore perspective not quest or gameplay.
