(nods) Yes, agreed with all of this.

And it is admittedly kind of funny that I can say "Superman is from Krypton, not from Vulcan!" and be understood as talking about a fictional character in a body of myth, but if I say "Superman really exists" nobody understands me the same way (though in the Superman mythos, Superman both really exists and is from Krypton). A parsing model that got that quirk right without special-case handling would really be on to something.
