In my opinion implementing the deletion of data in a way that can be forgiven by the user (and even worse API) is a bad idea. It's like burying unexpected clauses in the middle of a 50 page terms and agreements. It's definitely not illegal or reprehensible, but anyone doing *aaS has exponentially more knowledge than it's users and knows it. Anyone who has once tried not to impose minimum password complexity knows what I mean. To me it seems that data cleaning should be something you choose as you purchase the service. I understand that cost might be a factor in this particular case, but in then why not communicate about it and make a premium or discount system? It would probably come in good light to both users with sensitive data and those who don't care.
