Yeah, these hanger talk scenarios are absurd and they go to a level of absurdity regularly. MSP, JFK, LGA, and multiple other towers have clarified you WILL in fact wait for clearance before doing any published missed. We know because we've had guys go missed, fly the published, and go right into traffic.
Before we go into any other bizarre hanger talk about what ifs and, "but a fire", stop. Ils 31L results in a missed because you can't see the runway, you wait to be told to go published. Dead stop. Fly straight, climb, tell them youre going missed. FAA can't possibly be more clear with that. They can't.
