In Italy we have already digital IDs through SPID[1] which is most likely going to be phased into eIDAS and it works a similar way (though way less standardized), government websites can integrate it willy-nilly while private companies have to undergo quite a rough approval process to make sure they absolutely need that information.

Given the amount of already digital tech in our gov (we also have "legal mail" via PEC[2] and a bunch others minor standards) I think it would be insane if EU just went "nice work you have there, now scrap it all and use ours instead", so I see why component states still have so much authority (even if it means some will not have a good time).
