This is a pretty difficult problem to solve. Facebook would need to delete your data from production databases, database backups that were made while you had an account, caches and CDNs, etc. But even if they managed to delete the data in every possible place they could find it, a third party might have made copies of your data via Facebook's APIs some time in the past, and they might still have it.

So, even if Facebook offered such a feature, I wouldn't have much faith that it actually worked.
