This is concerning, but I still have faith in big orgs' and governments' inability to do a simple thing right while paying consultancies a lot of money for it. I have experience implementing banking infrastructure using eIDAS for participant identification and I know how CAs and financial institutions do not get eIDAS. They make rookie mistakes and deny they've done something wrong for months while blaming the other party and seeking regulatory exemptions. I'd be surprised if the EU governments were able to implement it. What wouldn't surprise me would be them blaming browser devs for it.
