19B Custom Security role issue for News feed implementation

Content

We received 19B in lower instance and I am updating my custom HR specialist role by comparing it with seeded HR specialist role. I see a lot of Manage and View aggregate privileges added to seeded HR specialist role which were earlier added to seeded employee role only and used for view and update own data for example "Manage Person Citizenship" and "View Person Citizenship". I have looked at docs.oracle.com and found those privileges added in document as well (see below). I am wondering why it is added to a HR specialist role which is usually a admin role.
