People seem baffled its gone for no reason, but I have long suspected the feature caused audio artifacts. When I would FaceTime friends, if I had the phone leaning against something, portrait oriented (so charging port towards table) I would occasionally get terrible artifacts in the call. I assume it had to do with some audio filtering thing causing feedback. It was def a software issue because it showed up one day multiple devices (me and friends and partner) after a major version update. So, maybe they took it out because the sound quality was impacted too much.
