I think the most important thing that it brings up is the awareness of what happened in the past. Also, it will add a layer of protection for this not happening in the future.
As you know, the Hazara people have been suffering for centuries. That is still going on. There's also no hope that it will be stopping soon in the future. Right now, as mentioned earlier, in some areas of Afghanistan, Hazaras are displaced; they were forcefully displaced by Kuchis. They own the lands of Hazaras during that genocide that happens. Nobody knows about that unless it is those who are connected with the Hazara people living in Afghanistan. That is an ongoing issue.
The main thing this will bring is another layer of safeguard towards the Hazara community to be protected and to not be targeted. Also, it will change the socio-psychological view and the belief of society, to not treat Hazara people as secondary citizens and to treat them equally, the same as other citizens.
