I have long found this reference useful, but it now seems to be under attack for not conforming to Wikipedia's norms.  I think new content added will struggle to conform to such, and this reference is far less useful if incomplete.  Hence, I would advocate for option 4 directly, before any more gets chopped up and people get frustrated with Wikipedia, moreover waste their efforts in a futile attempt to satisfy the rules.  Wikipedia doesn't seem to really want this kind of content, and there are other, stable Wiki's that do.
