Plus, most of what Real ID does is increase the documents that you need to show to get your ID. The state generally isn't then putting all those documents online somewhere -- it's just requiring that you show them to an employee at the time of application. So in terms of what's stealable by hackers, nothing has changed.
Edit: I’m wrong, the state is required to keep copies. It’s not required to keep digital copies, but that’s probably simplest and so…
