"First, we liked the one pot method because the community pot brought the Crew together. Second was the trash."
Any water boil method will bring a crew together via the use of a single community pot, whether using turkey bags or bowls/cups.
As to the second point, the 'footprint' a turkey bag leaves isn't that obvious. Sure, the trash is visible, but how does this compare to the impact of cleaning (presumably with soap) all those bowls & cups? Secondly, who wants to hoof water back & forth for clean-up? Those kinds of chores make backpacking less enjoyable.
Thirdly, if you use bowls, then you are sort of stuck using conventional dehydrated food (like Mountain House), unless you bring a lid & cozy. One of the key advantages to using turkey bags transcends the clean up vs trash debate.
With a bag inside a bubble envelope (for insulation), you can cook all kinds of standard home meals (ie non-dehydrated food), such as oatmeal, pasta, mac-n-cheese, etc, and let it sit for 10-15 minutes without getting cold. From a dietary stand-point, I think that factor alone makes turkey bags a lot more appealing.
