I also enjoy the passport section.
In addition to what you mentioned I think it would be nice to also see when you got the password (IE. the date when you first played be someone from that country), just as you see when you got an achievement.
Fun fact: I have have played 66 countries, but has yet to play anyone from my own country Norway. In the real world it is usually the other way around.
I think it would be awesome if under the passports section you could select a country and have it show how many players from said country you’ve played maybe even a win/loss stat
