Indeed; of course there are times it might be necessary to work around safety features. The problem happens when they are not labeled properly! When the end of the cable looks like normal with a standard connector, this type of workaround cable becomes an "attractive nuisance" that people will accidentally use. If you need to make a non-standard cable - especially if it bypasses safety features - you have a responsibility to mark the cable so anyone that finds it (possibly by accident) will understand the cable is non-standard and dangerous! (alternatively: destroy the workaround cable after using it) When I used to make an ethernet crossover cable, I would find some way to label it "crossover" and I would put 3 high-contrast stripes at each end with zip-ties so it was obvious looking at either end that the cable was unusual. A non-standard and dangerous power cable should at a minimum have big, obvious labels and warning indicators at both ends!
