It depends on future projections, which is difficult to predict. When miners shift from a block reward + fee based income to a fee based income + block reward model fees will inherently rise. But so should Bitcoin’s price. At today’s price I’d rather have a 1M UTXO with optionality to decide what to do with my UTXO change, rather than concern myself with smaller UTXO sets in a high fee environment down the road.
