Hi, Parent pages are there for the navigation aid. Backlinks help also in this area (there is actually backlinks activated on xwiki.com now although there are not shown in the interface) but are not really enough. Spaces are here for a macro level organization and rights. It would be too power consuming to handle rights using the parent fields and could also be confusing. Since the parent field is filled automatically when creating a page from another page it creates a navigation tree without actually requiring a lot of work from users. This has a lot of value in a bug wiki. We have some prototypes showing the navigation tree in a page or in a MindMap.
