Chrome OS settings should allow the user to reveal the saved password for any WiFi network the system remembers.
The use case for this is that people forget their WiFi passwords all the time and their computer may be the only device that remembers it. Resetting your WiFi password causes more problems than it solves because now every other device in the home needs to be updated as well.
Given that Chrome allows the user to view passwords saved for auto-fill there doesn't seem to be any security benefit to hiding saved WiFi passwords either.
