Well my contact said that the person who regularly deals with PEV policy is on leave right now. I'm not sure when they'll be back. He mentioned an organization call GrowSmart Maine that might be interested in this issue. They're focused on sustainable development. But they seem to be quite a small organization and probably wouldn't be able to help with smoothing things for Tesla.
Anyway, I'll at least email them and mention the issue of zoning of chargers.
Thanks. I think there are several routes underway, including yours, that will get Maine superchargers up and running before ski season (snow not water!)
