I wonder if the city of birth is relevant too for uniqueness. I imagine the collision prevention then falls in the hands of the city administration office. It'd be funny if there's a Hans Müller born on 31 May 2023 in Frankfurt, and another Müller family wants to register a Hans, also born in Frankfurt, also on the same date, they might say "Sorry, that name is taken already". Of course it'd be complicated if e.g. the 2 Hanses were born in a foreign country with no such checks, and moved to Germany later on...
