Why is this a topic of discussion. I do not think it is cause for concern when the stove is outside.
The reason it is being dicussed is because it is winter and when its cold and the wind blows and its getting dark and you are hungry it is not much fun outside cooking and eating.

All that is needed is a simple little chimney so you do not have to risk your life or health by taking the stove inside with no chimney.
The chimney has the added bonus of heat inside out of the wind.
We are talking 12 ounces more weight and maybe the comfort is not worth it.
