One relevant thing is that these forks are unnaturally narrow in all models, and rather resemble locks (not quite but close). From multiple possible continuations models tend to prefer just a couple, i.e. the model is a lot less random than it should be. That's why you're seeing annoying slop in writing and instantly recognizable color schemes in vibecoded sites. Lack of diversity probably limits the usefulness of this method as well.
