'Cannon' or not, it's Warhammer material, from the source. Not a third party parody, and whatever reasons you have for disregarding bloodbowl don't apply to sillier elements of Warhammer Fantasy itself. Regardless of how you cut it, the warhammer world wasn't 'Dark Fantasy', it was 'Everything Fantasy', in an attempt to appeal to the broadest possible range of fantasy archetypes, resulting in an anarchic, scattered, and frequently contradictory tone rather than any sort of unified singular vision, because Warhammer was always a backdrop for a game, not a coherent fictional world following any sort of unified vision.
The Warhammer World was not a work of art of and into itself. It is not a master's painting to hang in a gallery. It is, and has always been, a painted stage backdrop, the work of countless nameless stage hands, there to add just a layer of verisimilitude and immersion to the action of the play, a backdrop re-lit to match the tone of whatever scene happened to be playing out in the moment whether comedic or tragic. It is no great loss to the ages when it is repainted to set the stage for a new play, once the curtain has fallen on the old.
