- Handle skip_self in ObjectSecurity.reindex/reindexObjectSecurity
- Try and find a better way to handle when the reindexObjectSecurity method(s) get patched. Currently, we have a global ZCA utility 'managing' a SimpleItem tool which is site local. Previously attempted to conditionally initialise and persist the shadow tree tool in a GS import step, but this fails because reindexObjectSecurity is apparently called before import steps are executed.
