The big plus will be the ability to clear Russian fortifications hidden in tree lines. Currently the only way to clear them now is for the Ukrainians to drive up in IFVs under cover of artillery, dismount and fight at close quarters from dugout to dugout. With 155mm cluster shells the process should be much safer, with drones finding the Russian dugouts and artillery wiping out larger swaths of tree line with a few cluster bomb shells, with the benefit that Russian mines and IEDs can be detonated as well. After that the AFU infantry need just walk up, destroy any surviving forces and move forward.
Plus unexploded cluster munitions make it harder for the invaders to maintain those positions as they will present a lingering threat to Russian movement and action.
