Ok, I see your point. The question is if we scrap the rule altogether or if we add a further sentence like: This rule can be loosened to account for the VRA or for CoIs or in states where counties have little meaning (e.g. Massachussetts) or for cities with particularly erose borders.
^I think something like this is good. Counties are often good CoIs, especially east of the Rockies and South/West of Philly, and especially in rural areas. But in major metros and certain parts of the country (New England, the West, and to a lesser extent NY/SEPA/NJ) counties are less significant.
