Topic/Admin responsibility for a page

Error: Assign an “owner” to a page who is responsible for the page. I’d like this to be an Admin responsibility

Solution: A Responsible Editor can have special permissions on the page he is responsible for. E.g. You have a namespace where noone (but sysops) can edit. You assign a user as responsible editor to a page --> he, and only he, can edit the page if the "edit" permission is set for responsible editors in "WikiAdmin > Preferences > Responsible Editors"
