That’s adjacent to birth certificates and passports already, with some variations on a theme per country, but certainly I don’t object to it. But I’m still infuriated at having to provide a birth certificate to LinkedIn to support a legal name change, so I encourage further design at the interface between “citizen identity” and “online identity(s)”. Your idea has merits and isn’t like others I’ve seen, so it’s worth considering in more detail!
