Over the decades, "D&D Fantasy" has become its own genre. The reciprocal relationship between D&D and video games has not only embedded this sub-genre, but given it relatively consistent visual tropes and mechanical implementations. The decade or so of popularity of TSR setting novels also entangled the visual language of paperback fantasy with D&D -- even when the books had little or nothing to do with D&D fantasy -- and that is to say nothing of the generation of fantasists who grew up on D&D and its influence on their work.
What I wonder is: is it possible to disentangle D&D Fantasy from the game of D&D, to do D&D in a different or new flavor of fantasy? What would it take? Could D&D's "sacred cow" mechanics survive such a transition? What about its visual identity? Are there very D&D adjacent (OSR, OGL) games that manage it while still "being" D&D?
