What kind of grandfather clause do you imagine? The law basically says that companies are allowed to make you prove it's your data you're trying to delete to deter people using it to delete that of others. They're also allowed to refuse or charge a reasonable fee if they can justify that the request is spurious, unduly burdensome, onerous, etc. Yes, but obviously you've got nothing if you use an US-based service from the US. It's based around companies subject to EU laws, rather than any real notion of citizenship.
