There is a setting: showuseridentity which does this: "When selecting or searching for users, and when displaying lists of users, these fields may be shown in addition to their full name.". But - showing all these extra user fields as columns in a table is annoying because they are wide. So it would be good to add an option to hide these fields when showing lists, but show them when looking at a single user.

Also MDL-20250 introduces a setting to hide these fields specifically for the grader report for the same reason, so if this trend continues we will have 20 settings to do this for every place in moodle we show users in a list.
