I never saw any of those other platform names mentioned at all.

I would say it was the opposite way.....
Epsilon started its life as a mainstream platform for the Malibu, G6, Aura, etc. Epsilon II may have spawned a LWB version to replace the vehicles on the W-Body( Impala, LaCrosse) and G-Body( DTS), but I wouldn't classify Epsilon as a premium platform brought down to use for Chevy.
Now Alpha platform is one I would classify as that. Alpha platform was meant for Cadillac's use from the beginning. It's an expensive platform. The Camaro was then put on it as a way to spread the costs and why Camaro had a price disadvantage over Mustang and Challenger due to the pricey nature of the Alpha platform.
