Those are already in place in France, but some administrations still ask for a paper original (or scan of original) of your birth certificate. However some others have implemented some government-backed scheme where it automatically fetches your birth records from a government source (idk how it works behind the scenes) and it just works.

It was the same with a proof of where you live, it had to a be a bill in your name for electricity or something similar, but now it can just query popular sources such as the main electricity provider and just work.
