Yes, the idea would be to track the smallest set of privileges held by
anyone editing this page. You take the intersection of the page's
current permissions and the currently-editing user's permissions.
Another simpler solution is to make all the pages unowned, make new
pages unowned, and make them remain unowned even when edited.
However, that may not be a general solution as it is more restrictive
that it may need to be.
