Does someone want to do a Mediawiki extension for Google Summer of Code or the like to implement a riff on that?
It's applicable to more than just software development, and the software development it talks about includes collaborative documentation. I suspect that it is very similar to general accuracy maintenance automation, and it still works better with a human participant driving the process schedule (to the extent that human is skilled at it) but there are some very attractive opportunities for e.g. Wikidata and maintenance bot integration down the road if it works out.
