Oh nice, I was worried I’d have to start a whole discussion about doing this, but you took care of it already.

Are you sure boundary=political is the best tag for the counties? As I understand it, that tag is for things like congressional districts and electoral wards, which so far we’ve refrained from mapping. As far as I can tell, Connecticut’s vestigial counties don’t have any electoral purpose either. Rather, they remind me of England’s ceremonial counties, which appear to be tagged as boundary=ceremonial. But I think there’s more momentum behind boundary=historic for this sort of thing.

For the new planning region boundaries, the names of the COGs should be in operator=*, not official_name=*, and I think border_type=planning_region would be less confusing. The planning region is the service area of the COG, not the COG itself. By analogy, we don’t tag Australia as official_name=Government of Australia.
