Abhor may not be quite the right word, but they have.
There are at least two things widely used by hunters in bear country when one has to make multiple trips, often over a couple of days to carry out a large kill like a moose. But when backpacking, most of us don't want to carry a 1/2 lb of pepper to dump all over our tent before we pee on it and crawl in for safe night's sleep with our food.
