I used to think that, but recently had a really bad experience with a lot of runaround with them when we had to have our mail held for a few weeks while we sorted out a mailbox break-in. We would go to one post office that was supposed to have our mail and be told to go to another post office, then get redirected back to the first post office multiple times. And they kept talking about how they had to work out the logistics and everything was changing over and over. Some of the managers seemed to give my wife the wrong information to get rid of her.
There were a few managers who tried to help and eventually we got our mail but the way everything worked out was absurd. I think they could handle national digital identity except that if you ever have a problem or need special treatment to address an issue buckle up because you're in for a really awful experience.
The onboarding and day-to-day would probably be pretty good given the way they handle passport-related stuff though.
