There are
mods with wiki pages, and the
community CK2 to EU4 converter also has a page, so my interpretation is that modding tools are permitted to have pages on the wiki. For CK2, at least. (No idea about the other Paradox games covered by the Validator.) Reasonable enough?
I have a wiki account that was validated or some such a while back, so I might be permitted to make new pages. I haven't ever previously attempted anything anywhere near that large on a wiki, but probably it only needs a barebones page initially. If you're game for it, I could try? (Not tonight, because it's late, but tomorrow or later this week.)
