The chief problem is that once you have a question going and are getting answers, if it's deemed "not suited for SO", you're SOL. That question can't be moved to some "off-topic" forum, because there is no off-topic forum, because the entire platform is not a forum. I feel this situation can be resolved simply by making an unsuitedfor.stackexchange.com, declaring it not part of the official model (i.e. basically a gimped forum) and moving all non-factual questions there.
