By themselves, these extensions aren't that exciting (unless you are the kind of person who enjoys a machine-readable format of your wiki structure.
Like me who would like to download the wikis for offline reading in a non-offending manner. The graph XML seems to be even better than the Allpages in machine readable form (which I suggested a while ago).
But could Special:GraphStructure be ever a default feature? How badly it behaves with large wikis?
I guess the GraphStructure gives a better meta-access to the document than Allpages because the graph can preserve the document hierarchy.
