I'm not sure if it makes sense to have the Labs/OpenStack/Nova management interface on this same "new wikitech" wiki though. This means that all the community projects running inside labs will/might use this same wiki to document their internal structure - which can (and should be) a lot of projects that are not Wikimedia engineering projects.
Documentation for labs as being a Wikimedia project makes sense, but the actual projects inside and management maybe don't fit well inside the new wikitech. I like that of the labsconsole.
Do you mean they aren't *staff* engineering projects? Labs is meant to be a stepping stone. For most projects, the idea is that people will implement something in Labs and it'll get moved into production. The documentation for that project will then be the documentation for Labs and production.
One of the biggest reasons I wanted to merge the wikis is because I feel that volunteer operations engineers should be documenting their infrastructure changes in the same place as staff operations engineers.
