I must admit to doing something near as foolish. From the mid 70's to early 90's I used an Optimus 8r that seemed very innocuous and never flared, especially if you placed the fuel in the warming cup with an eyedropper. One morning in pouring rain, I decided to use the vestibule to make some coffee. The o-ring on the fuel valve failed and it started to flare up from the leak. Luckily I shut it down and it never got worse than a few inch flame that burned out. First and last time for that . I may experiment with some reflectix and use it both as an outer wind break/chimney with the foil still inside and as a cozy for meal re-hydration with some glued on velcro to create an envelope. Once again, not enclosing the stove and canister, just putting a partial windbreak/reflector up. Saves the time clearing and packing snow, or piling rocks. If I make some sleeves in the reflectix I can use snow stakes to hold it in place.
