Yeah I'm fairly confident that the NCAA would only take away autobids or whatever if conferences aren't able to find a warm body. The NCAA doesn't want to be a villain punishing low major division one conferences.
NCAA: "Hey you guys are losing (insert school here), what's the plan? You know you need (x) schools to keep an autobid"
League: "Hey yes we are adding (lower division school), they will be full D1 in a few years, is that okay?"
NCAA: "Oh, yeah. Sure. Sounds good. Well, I better get going. I have another scandal at a P5 that I will somehow not punish in any meaningful way."
