The Holocaust should be averted or end earlier. The Romani were proportionately the most devastated people by that genocide. Unlike with the Jews, where enough were left alive that remaining elites were able to capitalize on sympathy to build support for a Zionist state (it helps that the anti-Zionist Jews were either more likely to be dead or more likely to change their minds after the Shoah—the entire continent had become a mass Jewish grave), the Romani elite were almost totally killed in the Porajmos, leaving a community in shambles and vulnerable to continued marginalization. It was the most successful genocide of fascist Europe—large portions of Romani culture, which has a heavy oral tradition, have been fundamentally lost forever and Europeans don't know jack shit about it.
