It would be helpful if there was a permission/sub-permission that could be granted to roles to remove specific course roles from courses. The '<User Group> add / remove in courses' permission does not work for SIS imported course users. So when a role does not have the permissions necessary to manage SIS data, they are unable to remove teachers and other course roles added through SIS imports. This creates a situation where the 'SIS Data - manage' permission would need to be enabled for roles that need to remove SIS course users. However, the 'SIS Data - manage' permission is far more permissive than just user removal. Perhaps the '<User Group> add / remove in courses' permission could include and/or have separate checkboxes for SIS vs Manual users?
