If one person enters a deposit and someone else voids it, before it is posted, there is no record of the deposit. This potentially puts people at risk. Ex: If I entered a deposit and the person responsible for posting it, voids it, there is no way to trace where the money went.
While that is not an active part of the expanded History of Changes area in FE NXT, this would be a great idea if it is not already in the planning stages.
