Some things like Central City, Waverider, D.E.O, Arrowcave, Metropolis, Freeland (Earth-Prime), and others already have Earth-Prime pages. If Earth-Prime is a merged Earth, while United States should keep it's Prime Earth page because it has really changed to have Earth-38's National City across the water to Earth-1's Central City, the Arrowcave and S.T.A.R. Labs hadn't really changed.
