The Russian Federation retains Soviet borders

I'm not sure how much longer the Russian Federation could keep its Soviet-era borders. Given the rising ethnic tensions and separatism, the result could be a civil war that makes the OTL post-Soviet conflicts (like the ones fought in the Caucasus) look tame by comparison.
 
It also might have just amounted to an added stage in a different, slower disintegration of the USSR.
There may be some nations that decide to leave later on, but from what I’ve read, the treaty would have gave more rights to each republic, and was more of a confederation making me think there would be less of a push to leave.

Correct me if I’m wrong about what I’ve read about it, not 100% sure.
