yes and no. I had a pop up camper that had a 7 pin harness. The trailer did not have brakes but, it had a 12 volt battery that I could charge and run the fridge off the 12 volt system. you can also have interrior lights in a small enclosed trailer. Just 2 examples. If you can get the factory installed one I say ADD it without question.
to me it's as essential as air and cruise. should NOT be optional should be STANDARD.
