This might unironically be the only move the Baltics could make that would ensure the Russian-minority excuse cannot be used on them.Then like Germany all the Russian ethnic minorities will likely be evicted because no one wants russian minorities to be used as a pretext for invasion again.
Just like the germans before them.
It's not like there aren't records of who was moved into the country by the USSR's leadership, and this would amount to a long overdue illegal immigration matter finally be recitified.
