In Canada, the water heaters have the cold inlet at the bottom of the tank (on the side). No dip tube. That makes so much sense to me, I don't know why we don't see that type here.
Could it be because they are easier to replace if the bottom feed pipe doesn't have to be moved out of the way to get a new heater into position?
Could be just "the way it is" but I'd be interested if anybody can give a historical perspective.
Regarding the copper conductor used to bond hot and cold pipes, it's a good idea even if those pipes are not relied upon for ground. With few exceptions, every pipe in the house should be grounded to ensure it does not become HOT.--
