I agree that I have always found this to be a very dangerous practice and I have never encouraged it in any bank that I worked. You will find it pretty standard though for secondary market transactions.
We sell all on secondary and used to use the ROR form that had two signature blanks, one for receipt and one for confirmation of non-cancellation. Not getting the second one signed caused issues with secondary which wants every signature line signed.
Switched to an ROR that only has blanks for receipt signatures and disburse on the first business day after the three days expire.
No pushbacks or issues from secondary or examiners.
