EUDI has had various criticism with its approach for not supporting unlinkability (with the same attestation used across verifiers they can be traced to the same user).

There are some long Github threads in the official repo along with a PDF[1] of cryptographer's feedback about the privacy issues. Also covered in this[2] article.

This is unlike BBS+ which supports unlinkability and which was even recommended by GSMA Europe to such address downsides. In the Github discussions there seems to be pushback by those officially involved that claim BBS+ isn't compatible with EUDI[3] and there seems to be some plateauing of any progress advancing it.
