Versioning in Admin Backend

All changes within a Wiki should be transparent to changes - also what a admin does! Why is the admin-backend excluded from this important concept? IMHO all admin-settings should be subject to versioning making it easy to trace and proof date and time of changes and get back settings changed falsely.

This concept would also allow admins to enable users to change more settings within thier spaces in a much more open way - without defining special rights.
