Bingo.
Case in point: I'm currently in Hong Kong on business and when I leave the room I put my RMB into the room safe. While I don't normally need the hub or any cables, when I'm in a hotel room in Hong Kong, different story. Right now I've got my USB-C cable supplying power, I've got my HDMI cable hooked up to the HDTV, and I've got my ASUS ethernet-to-USB adapter providing both hard-wired internet to the notebook and acting as a router creating a room-sized private wi-fi network for my iPhone and iPad.
When I'm out of the room, one connection to unplug. When I'm back in the room, one connection to plug back in. The Apple accessory isn't an "adapter". It's the world's smallest and lightest docking station. It's one of the best features of the RMB. Leave the legacy ports behind when you don't need them, bring along a tiny dock when you do need them.
