I’m pretty sure UK security services can link bank accounts to you already. Hell, credit score companies like Experian already do it.
This is beneficial for public services and companies that need to identify you. Having a single ID for a person is a huge improvement. As an example, when we got married, my wife was simultaneously both her maiden name and my surname. There is absolutely no link between passport, birth certificate, driving license, etc.
You have to go around to all these different organisations and have them update the details. They all have different requirements for updating the name.
Having a single consistent mechanism for referring to a person in systems seems hugely beneficial for both the organisation and the person.
