No it’s aimed at reducing the weight added to the chain. It doesn’t limit utxo, if anything it encourages the breaking of larger transactions into several smaller ones which each add utxo overhead. So every spam incident contributes more to utxo bloat. Also by reducing the demand for block space even further by removing the large transactions you make it possible to stuff in many more utxos more quickly. An adversarial force could theoretically utxo spam the chain in 5-6 months to the tune of 200 million dollars and make running a basic node at home extremely challenging. While this could be attempted now the prescence of spam bids the cost up 10x and increases the time it would take by a large amount. Do you think the decentralization would be helped or hurt by losing all the pleb nodes 6 months post activation?
