I think Luna is one of a handful in the industry that is attempting to push the standards on this. While smaller gauge wires may do in theory, when they get cruddy, the efficiency drops way down. A friend does solar install, and he always goes up one or two sizes for recommended gauge. The thing is, under average conditions, a 14 gauge wire may do the trick. Cover the stuff with oxide and you're turning valuable battery energy into heat. It really doesn't cost that much more to make things bombproof. As funwithbikes said, a lot of the engineering is done on a home lawnmower scale --- while better engineering costs more than the average user wants to spend. As a DIY builder, you can build to any standard you want.
