How about this as a happy medium default policy: Rather than select UTXOs
based solely on age and limiting the size of the transaction, we select as
many UTXOs as possible from as few addresses as possible, prioritizing
which addresses to use based on the number of UTXOs it contains (more being
preferable) and how old those UTXOs are (in order to reduce the fee)?
