It's alright, it isn't against the rules to enjoy fanworks, nor i hate them in any way. And you're not the first one to mention it. My concerns about it are, it may cause confusion about its status as an official product or would make people want more doujinshi added to the wiki. Plus, the article was copied from EvaGeeks. So feel free to help or suggest other additions to the wiki and we'll see what we do with RE-TAKE.
I'm aware of that. The main problem is, Evangelion has more than one canon, so almost everyone would be both "alive" and "deceased" defeating the purpose of said categorization. We were supposed to separate articles into different canons, like Shinji Ikari (Anime), Shinji Ikari (Manga), etc, but said project never blossomed, sadly. Only then i can see those categories working.
