I'm not opposed to people using ->round_rate() if they want to
use it and it serves their purpose. Moving everyone to
->determine_rate() will be a long journey that has little to no
benefit for most drivers, so it's not like we need to force
everyone to use the determine rate op for new submissions so that
we can delete the round rate op one day.
