Has UTXO selection methods changed since activation of Segwit? Before Segwit, transactions were penalized higher fees for having more inputs than outputs due to the input size being larger despite those transactions actually decreasing the global UTXO set. Segwit corrects this incentive mismatch. Have wallets taken advantage of this by changing their coin selection algorithms?
Bitcoin Core's client has recently applied changes to their coin selection algorithms based on Murch's Master's thesis.
