I spend a considerable amount of time on the translation website. I found it stated that it intends to do something for any wiki platform. I find however that only one wiki engine is promoted while much of the functionality discussed is to be developed. What I have not found is why this wiki engine is to be used. I do not find why other engines cannot do the same thing. I think that several of the things you discuss are done in MediaWiki already so I am left with the question WHY ?
