Why are you being so contrary? Loads of controllers have wire shunts. Just because yours have changed doesn't mean everyone else has. Even so, I told OP how to deal with solid state shunts, which give more accurate results than soldering wire ones and is just as easy, though cost a couple of quid for the shunt.Controllers don't have loop wire shunt for many years. They are all SMD now.
When did you see one of them last time?
