> customers' legal requirements that data is fully deleted

Strange. I've only ever heard of legal requirements preventing deletion of things you'd expect could be fully deleted (in case they're needed as evidence at trial or something).

While not common, regulations requiring a hard delete do exist in some fields even in the US. The ones I familiar with are effectively "anti-retention" laws that mandate data must be removed from the system after some specified period of time e.g. all data in the system is deleted no more than 90 days after insertion. This allows compliance to be automated.

The data subject to the regulation had a high potential for abuse. Automated anti-retention limits the risk and potential damage.

You're thinking of "legal requirements" as requirements that the law insists upon rather than requirements that your legal department insists upon. You often want to delete records unrecoverably as soon as legally possible; it's likely why you wrote your data retention policy.

I had an integration with a 3rd party where their legal contract required we hard delete any data from them after a year. Presumably so we couldn't build a competing product using their dataset with full history.

Many privacy regulations enforce full deletion of data, including GDPR: https://gdpr-info.eu/.
