Like, there is no doubt that humans probably noticed that hot water in the ground cooked things that fell into them.
But, I'm going to go out on a limb here and say that it was probably someone with boiled water from that whole fire thing we figured out a while ago that invented the revolutionary idea of putting more than just a dead animal into the water.
I believe the authors are postulating about the behavior of pre-human ancestors without the capability to generate fires on demand. “The paper opens a window to stop focusing on there being fire or there not being fire, to say there are other ways to cook and we should be looking for them.”

Just a guess though.
