That's a lot of the rational behind my cooking gear. I read a good post on a British site last year about carrying a brew up kit. The idea is that if you're turned around, you can relax for a few minutes and make a cup of tea. Stopping to make tea or hot chocolate lets you run through the S.T.O.P. process with out having to admit you're lost to start it. Ever since I've tried to carry some sort of brew kit. From what I currently carry to the bare minimum of an MRE heater and hot beverage bag. The MRE brew kit weighs nearly nothing and fits in a coat pocket.
