I think replacing the wikitech pages with this tool is totally fine, as 
long as

* The new tool needs to cache like crazy, otherwise it's a ready-made 
keystone DOS.  (Maybe it does this already).
* The tool is easy to discover (possibly via a sidebar link in wikitech, 
for the short term).
* We still have an established system for users to write documentation 
for their projects (maybe by preserving the existing namespace for that)
** The new tool should embed a link to ^

Thanks for making this!  The callback-based page updates are something 
I've spent a lot of time on and, hence, I have some attachment and 
reluctance to kill them -- but, honestly, the OpenStack upstream have 
been unknowingly hostile to that callback system and I have to rewrite 
things with basically every release, so it will save me a bunch of time 
to not maintain them.
