So, on the Xbox 360 (and on pretty much every physical media player that has a remote control) I can remotely eject the disc from the console while I'm sitting on my sofa, and then by the time I step across to the console, it's already sticking out waiting for me.
There are multiple options to do this on the 360, either highlighting the default top-left tile and pressing Y, or pressing the "Open/Close" button on my Xbox Media Remote, or using Kinect I could say "Xbox Open Tray".
None of these methods seem to work on the Xbox One, I can't find any way to do it with the controller (I have tried selecting the disc tile in the bottom right and pressing the controller's menu button, but there's nothing relevant on there), there is no media remote, and nothing like that is listed in the new Kinect Voice Commands list.
Do I really have to stand up, walk across the room, and press the Eject button on the front of the console? Even my '80s VCR let me eject tapes from the sofa!
Edit: If you're interested in this, here are some requests on the Xbox User Voice site to vote on or keep an eye on:
