It’s a good job that’s not the intended use for it, then. 
It’s like those cast-iron dutch-ovens. Brilliant for making a roast in the embers with damper bread, but you’d need to be some sort of masochist to tote it with you if you’re planning on making any distance.
OTOH, if you’re set up in the one spot for some fishing or hunting, perfect.
Coming back to base to find a ready-cooked hot meal at the end of the day is a treat though. And as it says in the OP,
an awesome way to set a meal cooking at the campsite, while I go off and have an adventure.
So, yeah, if they were hiking the NW loop of Stewart Island, size and weight it would be an issue. They aren’t. It’s not.
