I also looked up the alleged reference to the great maw in one of the call of archaon short stories

the story is not about the maw at all, it's about some khorne warriors and then a gaunt summoner redirects ogres, who were summoning maw-portals to appear next to the khornates instead of wherever they were going to, making a mention of how this forceful redirection makes the great maw groan

>[the gaunt summoner scried] a while through the Realm of Beasts, a thousand scenes of strife and horror passing beneath its hands. In a land far away, it found what it sought. The ogor followers of Skargut burned to avenge the death of their master at the hands of Baudrax.
>They massed around their cook-priests, who at that very moment offered up the choicest offal to their hungry god, beseeching him to guide them to their foe.
>Maw-portals opened, red and glistening as gullets. The ogors screamed out their
desire for revenge and poured through.
>For one such as the Many-Eyed Servant, it was a small matter to manipulate such
simple magic and send the ogors where it willed.

>Somewhere far away in the Realm of Chaos, the Many-Eyed Servant heard an angry, brutish bellowing, but it paid the complaints no heed. The Ravenous One was feeble. Tzeentch was not.
