I've reviewed MDL-26882, in fact I'm running Moodle 2.2.5 so the changes have been implemented. I see now that in the participant list, the fields that I've selected now appear in table format.
I do not see the fields (like Institution and Department) appearing when I view the course or full profile of user.
I've ensured that my teachers, non-editing teachers, and students on my site have the capactity: moodle/site:viewuseridentity.
Perhaps I misunderstood the purpose of MDL-26882. How do I get optional user fields I've elected NOT to hide to appear in the full profile or course profile of a user?
