On Void Lords and Voidlords

Midnight and The War Within have shown us more of the Void and its inner workings than ever before, including our first encounter with a fully manifested Void Lord in Dimensius. During the fight we also encounter what seem to be two rival Void Lords who Dimensius has absorbed at some point, [Artoshion](https://wow.zamimg.com/modelviewer/live/webthumbs/npc/55/129591.webp) and [Pargoth](https://wow.zamimg.com/modelviewer/live/webthumbs/npc/33/129569.webp). The dungeon journal describes them as "conquered rivals", and both have the title "Conquered Lord". The interesting thing is that they are no more than giant [Voidlords](https://wow.zamimg.com/uploads/screenshots/normal/581057-grimoire-of-the-voidlord-voidlord-in-7-1.jpg), the Warlock glyph pets, which were of course full fledged regular summons in Mists of Pandaria and Warlords of Draenor with the Grimoire of Supremacy talent. Dimensius got a special model because he's big, has absorbed an unfathomable amount of material, and is the final boss, but the others are indistinguishable. Of course back in TBC when we fought what TWW revealed to be only a shard of him, he used that same model (or at least the classic version). Metzen also revealed in the introduction to the [Midnight Deep Dive](https://youtu.be/WmG98apVwKw?is=TfNTStpOct5cPE94) after the events on K'aresh that Dimensius was in fact the Final Void Lord, with the implication being that Dimensius had in fact absorbed all of his brethren, and those we fought within him were just the strongest.

I am growing increasingly suspicious that we've been wrong about the Void Lord/Voidlord distinction ever existing. It seems to me that the only difference between our little subjugated pets and the almighty forces of Shadow that frightened Sargeras into beginning his Burning Crusade is a matter of how hungy they were. If both Artoshion and Pargoth were rivals to Dimensius once, why not our pets? Perhaps we are all that stands between them and cosmic domination. Once again, Warlocks prove themselves to be the true unsung heroes of the cosmos.

Has Blizzard actually ever made a distinction between the two? Or is this more player headcanon that has got out of control because we all just assumed that they had to be different because if they actually had the potential to be that powerful it would be absurd?
