In 2019 1.4 million people migrated from one EU state to another [1], and 3.3% of EU working age citizens lived outside their country of citizenship (and that's rapidly rising - a 40% increase over the last 10 years) [2]. That's a baseline minimum of people who clearly need this. It doesn't count people who don't register because they only move temporarily (where it's not worth registering today because without such a system the paperwork can be a hassle!), it doesn't count migrants who now have citizenship in their destination country, it doesn't count the many non-working-age people who retire to southern europe, and it doesn't count people who interact with foreign EU governments for any reasons other than permanent residency. For example, you might want to securely access EU personal data while on holiday for health care (a digital EHIC), you might need to share your foreign driving license details with a car rental company, or your work may involve cross-EU business administration. This wallet won't be useful for everybody, but if it works well it would be a very valuable tool for many millions of people today, and likely many more in future.
