If you print out the username a web visitor only knows the username – which isn't all that hard to find out anyway. Minor security issue.
If you print out the real name a web visitor now knows the real name of your user. Minor privacy issue.
If you print out the user ID a web visitor knows the user ID. Medium security issue.
The most secure approach is to never show a username, real name, photo, user ID, anything. Of course that's outright impractical because neither the manager knows who says what, nor the user knows who answers to his requests.
So, no, this is the kind of feature request I am not willing to implement.
