Feature Request: Optional security score for each user

We are using Keybase more and more and as a security focused way of communicating, it would be nice if each user had a score next to their name that described how secure they've made their account. For instance if they have a large number of active devices, haven't verified their email, and use an insecure password perhaps their score is much lower than someone who has done those things.

It would serve as a reminder to keep your own account up to date while also helping to prevent you from sharing things with someone who may be lax in those regards.

It could be optional whether you want to display your score publicly or not, but doing so would make me feel better about sharing information with someone.

Start by discussing the scoring criteria and privacy implications with maintainers, including active devices, email verification, password security, and optional public display. Done would require an agreed design for calculating and presenting the score, plus tests covering the defined behavior.
