Like you said, it makes no sense for backpacking style of camping. Otherwise I guess you could justify the weight and water waste but I've never used one so I kinda think they're a hyped up trend personally.

Lots of weird stuff was being made during that time. I just hope that some of them still enjoy the outdoors and care about nature. If nothing else people who do go hiking/camping will be able to get some good deals when they sell all their stuff off because it was just a trend during covid for so many of them.
