I've got a 1.12 pack out, and I've definitely bitten off way more entity and AI mods than I can chew. Lycanites Mobs, Special AI, Special Mobs, Ice and Fire, Animania...

I've heavily customized and reduced Lycanites spawning, disabled spawner head mobs in Special AI, disabled sleeping in Animania until it's updated to fix a rodent AI bug, limited entity speed tick updates to once every 3 ticks in Iguana Tweaks Reborn (much more than that causes twitchiness), Enabled the "Calm down zombie guy" pathing delay in Random Tweaks, and just now disabled idle looking in AI Improvements. Hoping that's enough to make the single thread handling AI run at acceptable levels on a mildly OC'd i7 CPU without spamming tps errors skipping an average of 70+ ticks. XD

I'm not a fan of making sacrifices, even little ones. I figure there's not much need or reason for zombies (my biggest CPU hog) to turn their heads, but Animania critters lose a bit of charm if they don't. It would be nice if I could blacklist idle AI looking only for certain mobs.

Sorry for the late reply been busy and have been avoiding replying to all mod projects. We can set this on the plan to expand features down the road. I think I've partially implemented it already but never completed the functionality.
