Auditing Page Restrictions and Spaces

Having a way to see who in confluence changes permissions in Page Restrictions and Spaces would be very useful. Currently the data provided in the 'SpacePermission' table only shows users/groups that are added and permissions that are changed. However, if the user or group is removed from space permission, the record just disappears rather than show a user\group deletion type action.
Further, there is no auditing provided for Page Restrictions per link below. Any way to get these implemented?
