if I were the type to have the patience for wiki editing genuinely the FL guide I'd make would be called "Where to find commonly needed items based on where you are in the game" and it would be framed like one of those spoiler-free adventure game guides where you open little categories based on your progression and it points you straight at what's a good option for you
IMO the biggest weakness of the FL wiki is that it's designed for information completionism which means unless you're super turbo endgame you ARE going to get spoiled trying to look up where to get a candle or some shit
There are more point-and-click adventure games around now than there were in the widely remembered heyday of the genre, as are adventure games and other types of games that benefit similarly from an indirect, progress- and spoiler-sensitive approach to guides and information flow.
Irony: If you can ensure the system gives accurate information this is probably something you can program a chatbot-style hint interface for, maybe act like a discord buddy that played the game and knows your spoiler tolerances.
