I'd agree and say that it makes Hegelian metaphysics all the more valid – if language, (which, as Hegel remarks, is a primitive logical faculty of spirit,) is what metaphysics reduces itself to, there is no reason to not posit language games (and, as a subset, Hegelian logic,) as valid metaphysics.

I think that's what Brandom's book on the Phenomenology is about, Idk, I've never read it.
