Uhm... If some of my data is stored in one instance of that database and I then ask the owning company to delete such data in accordance to , say, GDPR... What happens ?
You delete it. You think there won't be a "I'm pretty sure I want to delete this?" option? you probably have to explicitly go out of your way to do it since the point is not to delete data.
There's probably also an option for not keeping history for data that it doesn't make sense to have history for.
