Hi Arty
Deleted in AGR_1251 really means deactivated. When you look in PFCG authorisations you will see the authorisations is red.
It means the generated profile for the role will not get the permissions in the role (and therefore, nor will the assigned users). You can reactivate it in PFCG.
You normally deactivate when it is a SU24 proposal that you do not need in the role but do not want to update SU24 either. That or, you temporarily want to remove it from the roles.
