There are two roles (plannermgmt and kiemgmt) which enabled some functionality which is now enabled in Security perspective under Workbench permissions (Configure Repositories, Promote Assets, Release Projects and Resource Planner).

These two roles have all the security settings enabled but cannot be directly used (without other role) for login to the workbench, so I think they loose their meaning.

If these role has no other function, I suggest to remove them because they might cause some confusion.
