One other character that sometimes uses an old chathead ani, is Armadyl in the new Eye of Het 2 miniquest. He had a few of those ones where it does a bit of speaking (like how it use to be) and pauses and looks like the croc here moving his head side to side. Im guessing it uses the same ani's ;)
That one has a fix ready to go out - as yeah, Armadyl doesn't have quite the same range of chathead anims as humans do :)
