I agree with the fact BL means nothing to the actual game, but the story with the firebelly and the maneaters was not from Black library but from forbidden power and entwined with gordrakk's story about that huge skull which probably is a hook to the next story arc in aos, and together with the community team saying in a post that the models are not going anywhere, I think the ogres are safe. Heck, if they are not removing the gorger why would they remove anything at all? That model is terrible.
