The CP AI is developed independent of the CBO - I test both to check performance.
I can honestly say that I only rarely see the 'lovefests' that are noted here. Generally speaking there are about 25% isolationist, 25% wiped out, 25% defensive-war, and 25% warmonger civs in each game, depending on map shape and size.

Well, then your experience is far from what I've seen and had, and from what I see in this thread and on these forums, I definitely am not the only one.
Every game (and I've played tens on this patch) there's DoFs, ranging from "everyone" to "almost everyone". A warmonger civ happens, yeah - once in two-three-four games. Unless you count me that is, then every game has a warmonger. The Smurfy circles I've mentioned before are back, but this time even going full-on Gargamel doesn't make anyone really hostile or mad. I've conquered almost the entirety of my continent and the friends of the conquered want DoFs with me still as I obviously prepare to take them over.
The other AI's at most be passive aggressive and declare the +33% unit maintenance congress thing, but that often hurts them too because some AIs just make huge armies they don't use.
In VP right now the status is as follows:
Situation normal - all's Smurfed up. Smurfs are love, Smurfs are life.
If the AI is to remain as it is, just hardlock it out of ever taking Authority and beliefs like Orders/Hero Worship so they are more efficient. No point in having them take something they won't ever make an use of, especially Hero Worship/Authority, though Orders at least buffs your Defense while Hero Worship needs you to conquer cities to do anything and Authority is inferior to Progress in everything if you don't fight hard at least in Classical era. As it stands, Authority/Hero Worship should be pretty much Player exclusive, just forbid AI from taking them unless they plan to fight by Classical and all will be fine.
I'd say forbid them from taking God of War too, but I only saw AI take it once I think and it was so long ago, I can't say if they fought or not.
Poor old Gazebo, looking for orgies in all the wrong places
At least he isn't looking for them in Civ 6 - it would prove he has some terrible taste because in that game everyone looks terribly ugly and barely human.
