It might help factions within Russia, or hurt factions within Russia. Not everything is about benefit for the country; in fact many things aren't. For example: continuing the war in Ukraine is beneficial to Vlad, or at least he must think it is to continue it over admitting defeat and withdrawing.

I can imagine Vlad or a faction aligned with him thinking this severs the ability for someone else displacing him to just turn on the taps, retreat out of Ukraine, and say "lol, whoops, our bad".

So the benefit may be to factions within Russia, even if it's detrimental to Russian economic capabilities.
