most of the usecase is going to be keyboard, mouse, and bluetooth headset dongles. All three of mine attached to my Steam Deck dock are USB-A.

although I own a bunch of those usb-a->c attachments you plug on the end, so it wouldnt make much difference

> bluetooth headset dongles

I imagine this has decent Bluetooth support out of the box even if not mentioned? Its hard to find a WiFi chipset these days that doesn't have some kind of Bluetooth support.

Maybe proprietary headset dongles, but if its just bluetooth its probably not needed.
