Metatron smugly claiming God left too many mistakes, that Metatron himself only knows the ending appears to me as though Carver himself (a.k.a. the new God/creator of the series) flips at Kripke's own take on the series (notice the parallel between Metatron's attempt to change the status quo and be the new God and Carver's relentless retcons on Kripke's work) and at us viewers/critics who hate the season and yet stick around for the ending (which Carver alone knows).
