A test page that matches the name of the wiki. This should actually work:
The wiki index has a blank route /wiki/
This page would have a route like /wiki/Wiki
While it would make it difficult to use a WIKI BB-Code to link to the index afterwards, allowing this enables legacy support for a "feature" in both NuWiki and VaultWiki 3, in which the wiki index was not actually a wiki page at all.
