Sure, but that isn’t how it works under GDPR. You don’t need to prove the information should be deleted, you need to prove the information must be kept. To give an example, the company I work for deals with long-lived contracts (often 20 years or more), and once they end we are legally allowed to keep the information for about 5 more years. After that we need to remove it.
Great idea, but the money they have is barely enough to make a dent in the development scope they are aiming for.
