I think we should keep the old universes as the home universe. They still came from Earth-1, Earth-38 and Earth-BL and readers who see the status as alive can guess that they are now on Earth-Prime. The only people who should have their home universe marked as Earth-Prime are the characters that are introduced post-crisis such as the new president, Marv, and Jonathan's brother. Jonathan's brother was created in the rebooted universe and we don't know where the president and Marv came from.
