I think it may also demonstrate to examiners that you're not just withdrawing the applications yourself....with no direction from the applicant. At my former bank, we prepared the notice out of the software because the notice is informative as to dates and reason for withdrawal, but we didn't sent to the applicants....just put in the files. At my current bank, we DO send the notices.
