If I had to guess, with so many devices (speakers, microphone, webcam) on top of any external ones you connect, having multiple inputs especially one that can't possibly connect your computer to those devices, is virtually guaranteeing that some users will complain that it doesn't work. I believe there is a similar reason why usb-c hubs rarely have downstream usb-c ports. When you do find one, they always have several reviews complaining that it doesn't work with 3 hard drives and 2 monitors plugged in.
