I wouldn’t mind them coming back, but only if they are more mysterious and eldtrich-like beings that people in the galaxy cannot comprehend versus being more or less a edgy mix of gith from D&D and Chaos Marines from 40k. The concept of the Vong is pretty cool, and having a mysterious alien species that’s not only dead and outside to the Force, but also has organic technology sounds dope af, but it would be a lot cooler if we knew less about them imo.
