It's very weird that USB-C solved the problem of "we can't tell which way to insert the plug" by mandating that both orientations should work, as opposed to just making the exterior of the plug as asymmetrical as the interior.
That's true, but the difficulty in that case comes from being unable to see the hole or fit into the space between the television and the wall.
For example, plugging an HDMI cable into the back of a monitor involves none of the difficulty of plugging an HDMI cable into the back of a TV, even though the connector and the port are the same in both cases.
Very asymmetric, impossible to plug in backwards, only one possible orientation.
Still absolutely fucking awful. Same for HDMI, displayport.
The RJ series are the only asymmetric connectors I've use that you can easily get in blind.
