Which time? When the Bolsheviks ousted a democratic government in 1921? When the Red Army crushed protests in 1989?

I get your implied point that Ossetians and Abkhazians did not feel included in the Georgian nationalist government that took over after independence, but I also think that Russia crafted the conditions that created this problem in the first place and intervention from them was not the solution.

the "balkanisation of Russia", like actual balkanisation, will be associated with a series of conflicts and death

Again, this is already status quo from Russia at the moment.

Also, genocidal is an overstatement.

A few days after the recapture, on 2 April 2022, news reports and videos emerged showing streets in Bucha covered with the bodies of men dressed in civilian clothes. Some of those found had their hands tied.[14][15] Among those killed were women and children. According to first estimations at least 280 bodies were found.[16] There was also evidence that Russian soldiers had systemically tortured, mutilated and executed many Ukrainians in the basement of a summer camp.[17] The event caused the Ukrainian government to call on the ICC to investigate whether or not Russia had committed war crimes.[18] On 7 April, the mayor of Bucha, Anatoliy Fedoruk, reported that almost 90% of the dead residents had bullet wounds, not shrapnel wounds.

In August 2023, the Institute for the Study of Warreported that the Ukrainian Resistance Center had claimed to have gained access to documents detailing Russian plans to conduct a decade-long ethnic cleansing campaign in occupied Mariupol. The ISW reported that the depopulation of Ukrainians through deportation and Russian efforts to attract Russian citizens to move to the city is likely to be an ethnic cleansing campaign in addition to being apparent violations of the Convention on the Prevention and Punishment of the Crime of Genocide.[83]

Russia has forcibly transferred almost 20 thousand Ukrainian children to areas under its control, assigned them Russian citizenship, forcibly adopted them into Russian families, and created obstacles for their reunification with their parents and homeland.[7][8]

These are genocidal actions, plain and simple. If you have a problem with me characterizing it as such I really don’t have anything else to say to you.
