It's not just a cosmetic issue. The people with the six inch cords are leaving them plugged into the laptop all the time as they walk around the building, just like the people with the USB-A ports are leaving their YubiKeys plugged in all the time.

The difference is that if they bump into somebody or something, that dongle is likely to get broken, and it could even damage the USB-C port in the MacBook. That's not going to happen with a Nano plugged directly into a USB-A port.

Right, it’s important that the whole world stand still for a decade because of some fucking “YubiKey dongle”.

Calm down. It's not just YubiKey. The world isn't moving to USB-C everything for a while yet.
