Yep.
GM tried out the mild hybrid waters a couple years ago. e.g. with the Chevy Malibu.
It was a failure for a couple of reasons: the EPA ratings were not improved enough over standard ICE to move the GM consumer given the extras cost of $1 - $2 thousand dollars, and people rejected the trade-off of no AC when the car was standing still. So far as I know, mild hybrids are also frowned upon in Europe for similar reasons despite the much higher fuel prices.
The one a couple years ago wasn't mild. And I figured it'd have an electric compressor like the Volt? (And I think why it was discontinued was a combination of most sedans flopping in the North American market (and it being a North American-specific product), and it using the Volt's hybrid system.) Previous ones were mild, though, and if you don't use an electric AC compressor, or run the engine to run the AC system, yeah, you'll lose the AC.
Here's the simple breakdown:
"Micro hybrid": BS marketing term that happened in the 2000s for a car (Smart ForTwo in Europe) with a start-stop system on the accessory drive in place of the alternator (and with no separate starter). Nowadays, this isn't considered a hybrid. Nor is a regenerative alternator strategy (that prioritizes charging under coasting/braking), you actually need propulsion to be considered a hybrid.
Mild hybrid: The electric motor performs regenerative braking and helps the engine, but cannot move the vehicle on its own. New mild hybrids usually have it in place of the alternator, but in the 2000s it wasn't uncommon to see it in place of the flywheel or flexplate.
"Full hybrid": The electric motor can move the vehicle on its own.
Plug-in hybrid: It has a charging socket to recharge the battery. These are almost always full hybrids (although Ferrari made one that normally operates as a mild hybrid!)
"Extended Range Electric Vehicle": GM marketing term for a plug-in hybrid that has full performance in electric mode - this is just the Volt. Note that this often requires limiting performance when the ICE is running - so the Volt was a EREV, but the nearly identical ELR didn't have those limits, and was faster with the ICE running and therefore was a PHEV.
"BEVx": California legal term for a plug-in hybrid that has shorter city range in ICE mode than it does in electric mode - this is the BMW i3 REx.
