I'm taking into considerations the meagre relative amount of reserves frozen there across the pond vs detained by Euroclear et al. These 5B won't do much help to Ukraine, where a roughly equivalent deficit emerged in the first fiscal quarter; and any interest accrued will be altogether minuscule, a decade at least is needed for it to form a lump sum. Euroclear, on the other hand, will quickly spiral into ever growing chasm after the reciprocal answer to similar confiscation measures; this (dismemberment of the European economic self-sustainability) is, to me, the true goal of the proxy war, but even European bureaucrats may seldom consider the backlash their policy would bring upon them, and nowadays are, by chance, the election season in the European Parliament.
At the next embedded level of complications, any intensification of financial sanctions against Russia, absent refactoring of their current silly design, will simply incentivize China to cooperate more eagerly, enlarging the sides of the Kissinger's triangle. Heartland snatches a leverage from Rimland.

That's why, whereas in the first act a glorious victory had been achieved (spring of 2022), further prolongation of the tin can's lifespan when being kicked down the road is untenable.
