I really don't like how EUDI (OpenID4VP) works in the first place. IMO it should be scrapped and rebuilt from the ground up

It should be an open standard that's local first. Government issues certificate, user loads it into any supported client app on any platform (official, open-source, Google/Apple Wallet, etc). The user should then be able to selectively share data from the certificate with third-parties, directly between the client-app and the third-party, using an open standardized protocol/format. The important challenge is that we obviously shouldn't have to share the entire certificate (which would include all data in it), there shouldn't be a static subject pubkey which creates linkability between data-shares, and obviously we'd need privacy-focused data fields like {"isover18": true} in addition to full DoB.
