My country has half-assed implementation but in general it has been great. For any signing I can just shove my personal id, enter pin and document is cryptographically signed. No alteration possible. And since government is the issuer of the certificate, no one can fake it. We have our e-government thing also, where you can do a lot of things, from checking your kids grades in school to theoretically handling all of the documentation you might need. Personal id is used to login into that service. Shove a card, enter pin and you are there. No sign up, remember password, etc. I have even set up, at one point, login into my computer using my personal id, out of curiosity as it held no other benefit. Had to add that root certificate to my machine though.

Sadly it all sounds great on paper, but execution is lacking. Some things still require pen and paper and it's annoying, but we'll get there. That's why my assumption is governments wanting to push for easier integration. Then all you'd need was card reader and a browser. Which also the reason why I don't think they are trying to push this idea for nefarious purposes. People download and install government software without thinking or double-checking all the time. Adding certificate through any installation wouldn't be much of a challenge.
