If you think about it, in places where landing the GEC in the meter is not allowed (because it's inaccessible due to the meter tag), there is no way to avoid paralleling the neutral with GEC's with multiple disconnects/panels.
In fact, with metallic service-cable conduits, the conduit itself always parallels the neutral. I wish we could use the meter's lug for the GEC, since it's already outside.
