I agree that if I attempted to power these items through the 12 ga line, I would have a flaming mess in no time
I understand that the gauge is not accurate. But as you stated, it never really was. All I want it to tell me is that the alternator is working, and that the batteries are taking charge properly with the needle slightly to the charged side. Basically, I didn't want a dead gauge in my cluster, and I was able to clean out some unneeded wiring from my engine bay.
