Decidedly. The First Raw pass hasn't a clue about what 'UNIQUE_DEMON' means. Actual world gen does.
I've just spent a few hours testing this, including with your mod, and I found it not to work like that. I only see the ear worms and heralds placed as megabeasts, and nothing but the procedural demons escaping hell. Do you have a save demonstrating this behavior?
*looks through what xml and saves he has* *snip down* I'm delusional.
The Tests I ran:
As is - Unique_demon, Megabeast(Difficulty and Trigger), No Other Funny Tokens.
Unique_Demon Removed, all others untouched.
Megabeast(Difficulty and Trigger) Removed, all others untouched.
Unique_demon, and Megabeast(Difficulty and Trigger) Removed, all others untouched.
Then I added in [DEMON] to test if I'd been playing with that. I didn't test with only that Token until later, but I'm snarkily confident that it's pointless to try with how similar .24 and .25 are.
Full is all my junk. Vanilla .25 and .24 are 'what it says on the box'. Nothing simply means "nothing escaped" - ie Spontaneously appearing on the surface and moving to the next step without a Wandering phase. Lair/Cave means it went out and added itself to a site population. Dominate means it fooled people into thinking it was a god, and then made itself leader/master/lawgiver/... papa smurf? Had to XML export means there was nothing in the Roc/Hydra/Dragon/Bronze Colossus section... not looking in FB or beyond... can't filter. Normal Pops just refers to the [DEMON] tag not say automatically making them 'Circus Vermin'

So it would readily seem that what I was attributing to [UNIQUE_DEMON] was one part delusion, and 2 parts [POWER] doing*its*job thanks to [MEGABEAST]. Yeah sorry for getting your hopes up Knight Otu... I'm not feeling my O's over here either. :/
As for 'depowering' stuff from Aspectus Lolin, I'm not surprised at all. It is .82 for a reason. Like GLaDOS I'm still testing. Just about every Modded in Civ is tweaked in Stats, Skills, and Skill Rates. Even just baselined 2's means that they'll never drop below 2 in that skill. One day there will be a release where they don't have any base skills, base stats, or atrophy rate mods. They'll entirely be personality and entity ethics based.
I'll probably still fight the Seputus in the raws... like I do now... the Eldritch Abomination worshiping things.
