This function is important due to the removal of the group pricing feature. For B2B stores this is a simple feature that would prevent the need for additional extensions for managing different pricing for different groups.
This would of course mean adjusting the logic of how pricing is shown in the front end, to only show that price and not do a crazy: $10, as low as $15 in the front end.
