Potential Security Issue

In looking at the course page, if you click on the Instructor’s name it brings up their profile. However, the URL for the instructor’s profile is using the profile’s username/login ID. IMO, this is a potential security issue as it exposes the actual login ID to the public. I think the URL should be built using the profile’s “Display Name” or “nickname” instead. Do you think this could be updated to keep usernames from being seen on the front end?
