These systems likely could be extended to just provide age information. If there truly was a wish for it. The suomi.fi systems can be configured. To pass or not pass address for example. So I see no need to pass personal identity number.

Yes and the "backend" (what provides the certificate to the app) for the age verification app for Finland will most likely be suomi.fi (or some dvv.fi thing directly) systems.

But we can't realistically expect every service that needs age check to work with 27 (eu countries) different systems but instead we need to unify it into a single api contract which is what this age verification app basically does.
