This question occurred to me while reading another thread. Rather than hijack that one, I'll ask here.

What is the advantage, if you are freezer bag cooking, to using a kettle instead of a pot? Some added ease with pouring, I would guess, but much less versatility as well, no option to heat a can of spaghetti-Os on a zero day if you want. Is there any other advantage? Aren't the kettles heavier? Less convenient to pack?

Just wondering. I've considered the option, but never convinced myself that there is any real advantage.
