I agree, the diabetic foot ulcers are fairly tame until wet necrosis sets in.
Cancer wounds are worse in my experience. The little old ladies who don’t go to the doctor until their breast looks like burnt bloody cauliflower and have been bandaging with toilet tissue or old tea towels for ages so you have to fish around in old macerated tissue to get all the threads and clumps out.
It’s a feature, not a bug. You can take them out to work on underground infrastructure, or even it out if there’s a slump, and replace the same materials, instead of having to jackhammer shit up and pour new concrete/asphalt.
